GIS spatial analysis and quantitative analysis of landscape indexes were applied to analyze land use features and influence factors of rural settlements in Panshi City, Jilin Province in view of the comprehensive regional environment. The results showed that (A) Rural settlements are mostly scattered, and concentrated in small groups, showing the co-existence and disorderly expansion of modern and traditional development features; (B) Layouts of rural settlements are closely related to agricultural production; (C) Rural settlements are mostly distributed in the linear patterns along rivers and in the ring patterns around reservoirs; (D) Distribution of rural settlements gradually expands to the neighboring areas of traffic arteries. Against the macro background of urbanization, studying the intensive utilization of rural settlements is a fundamental approach of relieving restriction of land elements, and also an important approach of promoting the construction of new socialist countryside, optimizing industrial structure and accelerating regional urbanization.
This paper first analyzes the general development trend and regional patterns of urban population and urban construction land in China from 1981 to 2009. Then it conducts a quantitative analysis on the coupling state between the growth rate of urban construction land and the urban population growth rate. Considering the status quo of urban development, it proposes that China should maximally optimize the allocation of land resources during the process of urban construction, so as to lessen the confl icts between the supply and demand of construction land.
