生態(tài)脆弱區(qū)土地綜合承載力時(shí)空差異分析——以榆林市為例
[Abstract]:Taking Yulin City, a typical city in the fragile ecological region, as an example, 30 indexes were selected from 5 carrying systems of society, economy, soil and water resources, science and technology, and ecological environment. The combined weight of AHP decision analysis method and entropy weight method is used to determine the weight of each evaluation index, and the temporal and spatial changes of the comprehensive land bearing capacity in Yulin City from 1990 to 2012 are analyzed, and the limiting factors of the comprehensive land bearing capacity in each county and district are obtained. The results are as follows: (1) during the period of 1990-2012, the comprehensive land bearing capacity of Yulin area showed a fluctuating upward trend, and the regional comprehensive carrying capacity of each county varied greatly. (2) in 1990, the comprehensive land bearing capacity of each county in Yulin was in the state of serious overloading and critical overload. The maximum value is Suide County, and the minimum value is Hengshan County. In 2000, the land bearing capacity increased to varying degrees, but the increase was not significant. The maximum value was Yuyang District, and the minimum value was Hengshan County. In 2012, the comprehensive land bearing capacity of each county was greatly improved. The maximum value is Shenmu County and the minimum value is Jiaxian. (3) the limiting factors of the comprehensive land bearing capacity of each county area are quite different. In 1990, the limiting factors were mainly scientific and technological systems; in 2000, the limiting factors were mainly economic systems; in 2012, the limiting factors were mainly soil and water resources and scientific and technological systems. Therefore, Yulin City should protect the environment and develop science and technology as the key to promote and maintain the coordinated development of society and economy.
