SPATIAL INTEGRATION ANALYSIS OF PROVINCIAL HISTORICAL AND CULTURAL HERITAGE RESOURCES BASED ON GEOGRAPHIC INFORMATION SYSTEM ( GIS ) — — A CASE STUDY OF SPATIAL INTEGRATION ANALYSIS OF HISTORICAL AND CULTURAL HERITAGE RESOURCES IN ZHEJIANG PROVINCE

In China historical and cultural heritage resources include historically and culturally famous cities, towns, villages, blocks, immovable cultural relics and the scenic spots with cultural connotation. The spatial distribution laws of these resources are always directly connected to the regional physical geography, historical development and historical traffic geography and have high research values. Meanwhile, the exhibition and use of these resources are greatly influenced by traffic and tourism and other plans at the provincial level, and it is of great realistic significance to offer proposals on traffic and so on that are beneficial to the exhibition of heritage resources based on the research of province distribution laws. This paper takes the spatial analysis of Geographic Information System (GIS) as the basic technological means and all historical and cultural resources in China’s Zhejiang Province as research objects, and finds out in the space the accumulation areas and accumulation belts of Zhejiang Province’s historic cities and cultural resources through overlay analysis and density analysis, etc. It then discusses the reasons of the formation of these accumulation areas and accumulation belts by combining with the analysis of physical geography and historical geography and so on, and in the end, linking the tourism planning and traffic planning at the provincial level, it provides suggestions on the exhibition and use of accumulation areas and accumulation belts of historic cities and cultural resources.


INTRODUCTION
In the previous researches on historically and culturally famous cities, towns and villages and so on, researchers often regard these heritages as a "sphere" to study its form, function, operation mode, and space layout.But if we look upon all these cultural resources as "points", especially when we mark all cultural resources within a certain range on the map as "points", we can see more information of space layout.The spatial distribution laws of these cultural resources at large scales are often directly linked to the regional physical geography, historical development and historical traffic geography and are of high research values.
On the other hand, in recent years, with the spread of concepts like cultural route and heritage corridor and so on, the protection and utilization of China's cultural heritages increasingly tend to regional collaboration and regional integration.For a province with wide space and multitudinous heritages, the exhibition and use of cultural resources are greatly influenced by province traffic and tourism and other plans, and it is of strong realistic significance to offer proposals on traffic and so on that are beneficial to the exhibition of heritage resources based on the research of province distribution laws.
Zhejiang Province is one of the districts with highly developed economy and culture in China since the Southern Song Dynasty (1127-1279), and it is abundant in historical and cultural resources.This paper uses the technology of GIS to analyze the distribution status of historical and cultural resources in the whole Zhejiang Province, aiming to reveal the spatial distribution laws of the heritages resources in this region so as to make proposals to the province-level management and rational planning and utilization of heritages resources.

General situation of Zhejiang
Zhejiang is located in the south wing of the Yangtze River Delta of the southeast coastal region in China.With a land area of 105.5 thousand square kilometers, it is one of China's smaller provinces.
Zhejiang has a complex terrain, tilting from southwest to northeast, and it can be divided into 6 regions including the plain in northern Zhejiang, middle-elevation mountain and hills area in western Zhejiang, hills in eastern Zhejiang, Jin-qu basin in the middle of Zhejiang Province, mountainous region in the southern Zhejiang and southeast coastal plain and coastal islands.The eight water systems consisting of Qiantang River, Ou River and Ling River, etc., and the Zhejiang section of Grand Canal flows through the province, forming natural ducts for regional communication.With four distinctive seasons and plentiful rainfall, Zhejiang belongs to subtropical monsoon climate and is one of the districts with highly developed economy and culture in China since the Southern Song Dynasty.It is the typical Jiangnan Watertown and is known as the "Home of Silk" and "land of fish and rice".
Zhejiang possesses a sea of historical and cultural resources, and its protection and management level of cultural heritages is also at the top of the list in China.Currently Zhejiang in total has 9 national historical and cultural cities, ranking third, next only to Jiangsu and Shandong.In the third national archaeological survey, with over 73 thousand cultural relics, Zhejiang has the richest "family property" and has 8 thousand more relics than Henan Province (the second place) does.

Density analysis of Zhejiang historical and cultural resources
In China, historical and cultural heritage resources include historically and culturally famous cities, towns, villages, blocks, immovable cultural relics and the scenic spots with cultural connotation.The research scale is the whole Zhejiang Province, so we screened the levels of its historical and cultural resources, mainly investigating the national-level and provincial-level historical and cultural cities, towns, villages, scenic spots and blocks with relatively higher values and greater influence and the Chinese traditional villages and major historical and cultural sites protected at the national level.
We firstly imported all resource points in Zhejiang Province into GIS according to longitudes and latitudes, made weighting and assignment on the basis of the levels and values of resources, and then obtained the Zhejiang provincial cultural resource distribution and density map.

Through superimposition analysis it can be observed that the patches of higher historical and cultural resource density in

Proposals for provincial transport planning
If the density distribution chart of historical and cultural resources is superimposed on the provincial traffic map, it shows that: The spatial distribution of provincial air harbors primarily meets cultural tourism demands, but Jiaxing Airport and Lishi Airport have not yet opened and therefore need to promote the construction.

Proposals for provincial transport planning
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XLII-2/W5, 2017 26th International CIPA Symposium 2017, 28 August-01 September 2017, Ottawa, Canada If the density distribution chart of historical and cultural resources is superimposed on the provincial traffic map, it shows that: The spatial distribution of provincial air harbors primarily meets cultural tourism demands, but Jiaxing Airport and Lishi Airport have not yet opened and therefore need to promote the construction.
Highways within Zhejiang Province basically connect the resource accumulation areas together, but the accumulation area between Jiande and Lanxijian has not yet been covered by highways.
Railway lines connect the major central cities in series, but the Songyang accumulation area and Jiande-Lanxi accumulation area which have the densest cultural resources have not covered.
According to the 2011-2020 Urban System Planning of Zhejiang Province, all the above transportation problems have been added to the future planning.We suggest gradually improving transportation infrastructure construction in accordance with this Planning, and paying close attention or giving priority to the construction of Jiaxing Airport and Lishi Airport and also the construction of Quli Railway, Jinjian Railway and Hangjianqu Railway.

Figure 2 .
Figure 2.Distribution and Density Map of Cultural Resources2.3 Correlation analysis of Zhejiang historical and cultural resource densityIf the density analysis chart is superimposed on the administrative city map of Zhejiang Province, it shows that the distribution density of Zhejiang historical and cultural resources is related to the distribution of administrative cities.In Zhejiang northern region, especially, administrative central cities in general are the cores in historical and cultural resource distribution.It is because Zhejiang modern administrative central cities develop basically from historical central cities, and these cities have profound economic and cultural accumulation and abundant cultural resources.

Figure 3.The Gathering Map of the Culture Resources Density and Districts in Zhejiang ProvinceIf the density analysis chart is superimposed on the topographic map and drainage map of Zhejiang Province, it can be seen that the areas in Zhejiang with dense cultural resources are in the riverside and especially in river confluence reaches.Therefore, the river, as the natural and traffic resource that is necessary for human existence and development, plays a fundamental role and tandem role.

Figure 4 .
Figure 4.Overlay map of cultural resources and ancient traffic It is worth noting that in the density analysis chart Zhejiang southwestern mountainous area cored with today's Songyang County has a large-scale dense district which strays from major central cities and the historical traffic line.After examining the data we can find that, on the one hand, it is because Songyang County does reserve a large quantity of cultural resources and especially Chinese traditional villages, and on the other hand, this profits from the Songyang County government's high attention to this work.Songyang in 2015 was awarded as China's first demonstration county of traditional village protection and development, which further motivated Songyang's protection work of traditional villages.Hence the density is impacted by certain policies and human factors, and its inherent laws are distinct from other patch densities.
Zhejiang have their own internal logic and reasons, and according to the density and internal logic we get 6 accumulation areas and 4 accumulation belts of Zhejiang historical and cultural resources, which are: Accumulation areas: a. Songyang cultural resources concentrated area, themed with the traditional villages characterized by the southern Zhejiang.b.Hangzhou cultural resources concentrated area, themed with the ancient capital and human landscapes of West Lake.c. Lanxi-Jiande cultural resources concentrated area, themed with the construction landscape characterized by the western Zhejiang.d.Shaoxing cultural resources concentrated area, themed with the Yue culture and modern celebrity culture.e. Ningbo cultural resources concentrated area, themed with the Hemudu Site and sea silk port culture.f.Huzhou cultural resources concentrated area, themed with the canal culture and waterside culture.

Figure 7.The Distribution of Lineal Cultural Heritages in Zhejiang Province4.2Correctional proposals for provincial tourism planningThe urban system planning of Zhejiang Province specifies its tourism development pattern of 'three belts and ten areas'.Combing with the analysis of above historical and cultural resource density and accumulation areas and belts, we suggest that the Zhejiang Province tourism pattern may make the following adjustments: We suggest adding Tang Poetry Road cultural tourism belt and upper Ou River cultural tourism belt on the basis of the existing "three belts" which are Hangzhou Bay cultural leisure tourism belt, eastern Zhejiang coastal and marine tourism belt and southwestern Zhejiang landscape and ecological tourism belt.

Figure 8. Culture Resources Density and Tourism Development Plan in Zhejiang Province For 'ten areas', we recommend bringing the human landscape of Fuchun River into Hangzhou international leisure tourist area, adding the themes of Maritime Silk Road and modern cultures to Ningbo Hemudu-Dongqian Lake tourist area, increasing the scope of Wenzhou Yandang Mountains-Nanxi River tourist area and bringing Wenzhou, Ruian and Pingyang and other areas into it, absorbing Lanxi area into Jinhua business cultural tourist area, building Taizhou Tiantai Mountain and Shenxianju tourist areas by combining with the Tang Poetry Road, and bringing Songyang area and Longquan area into the Lishuilvgu custom tourist area.
