Research On Regional Land Resources Comprehensive Carrying Capacity

Densely populated regions of China have become the most prominent problem in the present land use. Land resources is a certain time, place and conditions, to achieve its economic value as sources of wealth of the land. Land directly bearing the human social and economic activities, It is a complex land use system based on land-based natural, economic and social, economic development rapidly, resource shortages, environmental degradation, population growth and other problems caused by a series of increasingly prominent people and land, causing human pondering the limited carrying capacity of the land.As the capital of Guizhou Province, Guiyang City, is the political, economic and cultural center of Guizhou. The special topography of Guiyang not only brings unique natural ecological environment, but also restricts its economic and social development. Current land use has a range of issues, including:small land stock, low per capita land reserve resources are scarce, serious soil erosion, land use structure adjustment difficulties, growing difficulties in ecological protection; land Contradiction is quite prominent, Land carrying has a huge pressure.Through the analysis of land use in Guiyang, build the land evaluation index system of comprehensive capacity of Guiyang City, integrated land carrying capacity by Guiyang City Index. This analysis of current situation in Guiyang comprehensive carrying capacity of land, and then discusses how to improve the comprehensive capacity of the land proposals and measures.This paper is divided into four parts:The first part includes chaptersâ… andâ…¡. The first chapter is an introduction, an overview of the land carrying capacity of the research background, purpose and significance of research progress and research methods and technical articles routes. The second chapter is the theory of land carrying capacity, discusses the basic meaning of land, the concept of population carrying capacity of land, and focuses on the meaning of land carrying capacity and comprehensive research. The second part is the third chapter introduces the natural condition of Guiyang City and socio-economic generalizations. From the geographical topography, climate, hydrology, mineral resources, soil and vegetation, history, industrial development, population status, living standards, environmental quality show different angles of Guiyang status quo. With an emphasis on land use in Guiyang City, and analyzes land use and limitations of the main problems in Guiyang Integrated carrying capacity of the land factor.The third section includes Chapters IV and V. Chapter IV construct Guiyang Integrated land evaluation system capacity to meet the needs of Guiyang actual from the natural, economic and social point of view of 21 selected evaluation factors, the mean square decision weights determined using the comprehensive index of Guiyang City, and the county received integrated land carrying capacity. Chapter V According to the results, synthetic capacity of the land status of Guiyang City and county land carrying capacity for different strengths and weaknesses help to improve the bearing capacity of proposed opinions.The fourth part includes chapters VI and VII. Guiyang Integrated Land for increased carrying capacity measures and suggestions put forward the hope that through population control, adjust the industrial structure, coordinating the development of industrial agricultural economy, to develop a scientific land use planning and to strengthen the application of modern technology and other measures to increase the dynamic order Integrated land carrying capacity.Through the above study, get the following conclusions:(1) Comprehensive carrying capacity of the land in Guiyang main factors:natural conditions, poor location, the ecological environment is fragile; slow economic development, infrastructure lags behind; the obvious contradiction between people and land, low population quality.(2) Comprehensive carrying capacity of land Guiyang index is 0.4791. The maximum is 0.5749 of Yunyan District; the lowest value is 0.3978of Xiuwen County. The higher the natural carrying capacity of land has Kaiyang county, Xiuwen County, Xifeng County, Huaxi District, Qingzhen City, Wudang District; land economic capacity and social carrying capacity of land was a positive correlation, that is, the more the land of economic capacity High, the higher the bearing capacity of the land community.(3)Integrated capacity index of land can be consolidated capacity of Guiyang City, is divided into three grades of land, namely low, medium and high. Synthetic capacity and low areas include the Xifeng County and the Xiuwen County. The secondary comprehensive capacity areas include Hoaxi District, Baiyun District, Kaiyang and Qingzhen city. The Advanced Integrated Capacity Areas, include dolomite area, Nanming District, Wudang District and the Xiaohe District.
