The Intensive Utilization Of Cultivated Land In The Southwest Frontier

The land is the material basis of the development of human society can be saidthat all human production activities must rely on land. As a resource, land is afundamental human survival and development, and its importance is self-evident. Thearable land is the essence of the land resources and material wealth of human societycan not be replaced, but as a scarce resource, its quantity and quality is limited. Howto use the limited arable land to meet the population and rapid economic developmentneeds to become the focus of world attention.This article based on intensive land use are more representative of the borderareas of Yunnan Mans, for example,2010Mans Statistical Yearbook data Manstownship for the evaluation unit, the establishment of regional intensive land useevaluation of the property and spatial data, to establish the relationship betweenproperty and space. The build PSR "pressure-state-response model based on thecomprehensive evaluation index system, and the proportion of the relevant data werenormalized using the subjective weighting of the analytic hierarchy process toevaluate the extent of intensive land use within the study area. The degree ofcoordination and intensive use of a comprehensive evaluation.Utilization first Mans arable land intensive in-depth investigation and analysis,relevant experience of home and abroad on the intensive use of land evaluation,combined with the southwest land use status, with intensive use of land evaluationtheory and the intensive use of arable land evaluation ideas. Mans various townshipsof intensive land use to measure and get the status of the Mans intensive land usespatial differences. PSR model as a basis, the selected evaluation, and analysis of thecontrast Mans Land Use in the intensive utilization, and constructs the appropriateintensive land use evaluation system to better protect arable land, to address thecontradictions of the people and land, the development of border economic provides acertain basis. And using the analytic hierarchy process (AHP) to determine the TheMans arable land intensive use of the index weight, the overall evaluation of the theMans regional intensive land use, research intensive land suitable for arable use, andmake appropriate recommendations for the existing problems and countermeasures.At the same time, analysis and evaluation of the Mans regional farmland intensive utilization levels, to build the evaluation model, is estimated at this stage Mans arableland intensive degree of utilization.Mans each of farmland intensive use of the level of composite scores, accordingto the township factor Mans arable land Use Intensity is divided into five: arable landuse intensity is greater than80%of the highly intensive; utilization greater than60%,less than80%, greater than40%as moderately intensive; utilization, less than60%,low-intensive; greater than20%, less than40%compared to the extensive; utilizationis less than20percent, compared with transitional extensive.
