和墨洛綠洲鄉(xiāng)村聚落空間格局及演變研究
[Abstract]:In the process of urbanization, the spatial evolution of rural settlements intensifies, so it is imperative to organize and reconstruct rural settlements. The evolution of settlement in arid area is characterized by independent and complete regularity, and it has new characteristics in the process of oasis urbanization. Taking Xinjiang and Muruo oasis as examples, this paper uses GIS spatial analysis methods such as nuclear density estimation, nearest neighbor index analysis and buffer zone analysis to analyze the spatial evolution characteristics of rural settlements in Heluo Oasis. The characteristics of the present situation and the influencing factors are explored and analyzed. The main conclusions of the study are as follows: (1) the spatial pattern of rural settlements in Muruo Oasis shows a trend of continuous expansion from the center to the periphery, with obvious regional differences. Before 2000, the "single core" growth of Karakash Town was strengthened; From 2000 to 2010, the density of settlements in Karakash town as the core area decreased gradually, and gradually increased in Bagchi Town and Shauerbuge Township as the core area. From 2010 to 2014, the density of "binuclear" settlements increased, and the distribution range of high density of settlements increased obviously from the center to the periphery. (2) the spatial distribution of rural settlements in Muruo Oasis was highly concentrated. Most of the counties and rural settlements along the river coast all show the pattern of agglomeration and distribution. However, the rural settlements in the interior of the oasis, represented by Hotan City, showed a certain random distribution pattern. (3) the spatial form of rural settlements in Muruo Oasis showed two forms: scattered village and agglomeration village. Most of the settlements are distributed in the core of oasis in the form of agglomeration villages, along the river and along the road. According to the settlement location and density and morphological difference, it is divided into low density strip in low mountain valley zone, low density strip in desert hinterland along river, and high density strip in oasis along canal. The distribution pattern of high density strip along the oasis. (4) the rural settlements of Muruo oasis show obvious spatial differentiation law. The settlement density in the west of the oasis is obviously higher than that in the east, and the settlement scale becomes smaller from the west to the east, and the settlement density decreases gradually from the center of the oasis to the periphery, showing a certain central distribution characteristic. (5) the formation of rural settlement spatial pattern in Muruo oasis is restricted by the natural geographical conditions of oasis, economic development factors and social and cultural factors. The natural geographical environment is the environmental basis and leading factor for the formation of the spatial distribution pattern of rural settlements, among which water resources are the most fundamental factors restricting the spatial distribution of rural settlements. The spatial layout of national highway and county highway has a great influence on the settlement spatial pattern, which is the external factor for the formation and development of the rural settlement spatial pattern. The traditional and traditional marriage of farming culture in oasis, the conception of fertility has a great influence on the spatial pattern of settlement, which is the internal cause of the formation and evolution of the spatial pattern of rural settlement. (6) aiming at the characteristics of the present situation and the main law of evolution of the spatial pattern of rural settlement. From the aspects of industrial development, urban construction and village and town management, the countermeasures and suggestions for optimizing the spatial pattern of settlement are put forward. Actively guide the industrial transformation, develop high-efficiency agriculture, strengthen the secondary and tertiary industries, strengthen the construction of small towns, promote local urbanization; Strengthen the planning of villages and towns, improve the level of land resources, water resources development, management and utilization, and promote the harmonious development of the relationship between people and land.
