| With the rapid development of urbanization,the spatial evolution of rural settle ments is changing more and more frequently,it is imperative to carry out land consolidation and spatial reconstruction of rural settlement.The development and evolution of rural settlement in Hemoluo oasis is more independent and complete,and it shows some special characteristics in the River Basin spatial scale of arid area and new characteristics unceasingly in the process of urbanization in the oasis area.This paper takes Xinjiang Hemoluo oasis as an example,explores and analysis the evolution law,the status of rural settlements spatial pattern and the influence factors of the characteristics in Hemoluo oasis area,mainly used GIS spatial analysis method,includes Kernel density estimation,Nearest neighbor indicator and Buffer analysis method.The main conclusions of this paper are:(1)It shows the trend of expanding from center to periphery and obvious regional difference in the evolution process of Hemoluo oasis rural settlements spatial pattern.The first stage is a stage of Karakax town growth and intensification before 2000.2000-2010,The density of the original growth pole Centered on Karakax town decreased gradually,and the density of the new growth pole which located in the middle of Bageqi town and Xiaoerbage Village gradually increased.2010-2014,the density of two growth pole growing,while the high density distribution of the settlement significantly expanded from the center to the periphery.(2)The rural settlement in Hemoluo oasis shows the spatial pattern of highly concentrated distribution.it shows typical cluster distribution characteristics when taking the county area and river basin region as the reference scope,but it shows the spatial characteristics of random distribution in the heartland of oasis represented by the Hotan city.(3)The rural settlement in Hemoluo oasis shows two spatial forms: the unorganized village and the clustered village.Most of the settlements are distributed in the core area of the oasis in the form of clustered village,which is characterized by the typical banded distribution along the river and the road.According to the location,the density and the shape differences of the settlement,it can be summarized as four models: Low density belt in low mountain valley,Low density belt along the river in the interior of desert,High density belt along the canal in the interior of oasis and High density belt along the road in the interior of oasis.(4)It shows obvious spatial differentiation characteristics of rural settlements.The density of settlements in the west of the oasis is obviously higher than it in the east,and the size of settlements gradually declined from west to east;The density of settlements gradually declined from center to periphery,and it shows the characteristics of central place distribution;The density of settlements in different locations of oasis shows obvious regional difference.(5)The formation of spatial pattern of rural settlements in Hemoluo oasis area was restricted by natural geographical conditions,economic development factors and social cultural factors.The geographical environment is foundation and the dominant factor of the formation and evolution of distribution pattern of rural settlements in Hemoluo oasis,Water resources are the most fundamental factors that restrict the spatial distribution of rural settlements.The spatial distribution of State Road and County Road has great influence on the settlement pattern,is the external factors in the process of rural settlements spatial pattern formation and development.The tradition of oasis farming culture and concept of traditional marriage and fertility have a great influence on the settlement spatial pattern,which is the internal cause of the formation and change of rural settlement spatial pattern in the factors of social and cultural.(6)According to the present situation and the main evolution law of the rural settlement spatial pattern,this paper puts forward some countermeasures and suggestions to optimize the spatial pattern of the settlement from the aspects of industrial transformation,urban construction and village-town management.Actively guide industrial restructuring and develop efficient agriculture,strengthen the second industry and the third industry.Strengthen the construction of small cities and towns,promote local urbanization.Strengthen the planning of villages and towns,improve the level of development,management and utilization of land resources and water resources,and promote the harmonious development of man-land relationships of rural settlement. |
