Ecological Land Arrangement Potential Evaluation And Application

Implementation of land consolidation and rehabilitation work is less more thanthe Chinese, the important measures to guarantee food security. And with thedevelopment of society and economy, increasingly fragile natural ecologicalenvironment system and ecosystem requirements has become necessary in the currentland consolidation work requirements. Yanqing ecological land arrangement potentialevaluation based on regional development positioning, calculates the potential, thussorts through better planning and guided activities carried out.Based on summarizing the existing research on land consolidation potential, onthe basis of the literatures on ecological limit requirements, puts forward cultivatedland consolidation potential evaluation index, establishing evaluation system, so as toevaluate the ecosystem area of cultivated land consolidation potential.Taking Yanqing area as the research example, analyses the characteristics of itsregion, the region is a typical mountain area, terrain northeast high, southwest low, tothe mountains in southwestern basin; On land use pattern, based on dry land is givenpriority to, more concentrated distribution in the plains of central and southwestregions, relatively less area; Within the eastern mountain or sporadic distribution ofcultivated land along the river valley.For arable land consolidation potential evaluation, fully elegant area of climate,topography, soil, land use status quod, natural ecological system conditions, such asthe regional soil, terrain, slope preliminarily divides the evaluation unit, thequalitative judgment of cultivated land arrange is not suitable, reserve cultivated landconsolidation potential area, cultivated land arrange backup resource shortage area.Reference before the new cultivated land coefficient of land development andconsolidation project, in the regional land use status can be seen as sources of weedsto the number of new land for quantitative evaluation indicators, measuring the areaof cultivated land consolidation potential, the administrative divisions to partitiondelimit the boundaries of regional potential.On the basis Measure in Yanqing of cultivated land consolidation potential in ecology and sustainable development theory as the instruction, analyzing thecharacteristics of the Yanqing land use present situation and existing problems,combined closely with and rely on Yanqing land use overall planning, ecosystem inYanqing the planning of land management. On agricultural land consolidation andland comprehensive improvement of comprehensive balance, in the county within thescope of the planning of land reclamation, dividing the key improvement areas andkey improvement project, to Yanqing land reclamation development provide effectiveguidance in the future.In the process of research, with the establishment of natural limit index and realqualified index as the main evaluation index system of evaluation, evaluate theecosystem area of cultivated land consolidation potential, and thus to carry out theplanning of ecological land management.
