Ecological Planning And Evaluation Of Land Regulation Based On Landscape Ecology

Land as a human activity carrying resources to support the continuous development of human society, it is very important, land ecological problem is an important part of the country, regional ecological problems fundamental component. The rapid development of China’s economy, the increasingly prominent contradiction between human and land, a serious shortage of reserve cultivated land resources in China, the population and the food security problems faced by urban development, countries should introduce the land reclamation project, this paper studies the land reclamation project of narrow) to improve agricultural production infrastructure, improve and improve the quality of cultivated land, so as to realize the cultivated land protection. But since our country land renovation project implementation over the past 15 years, the present stage of land reclamation projects tend to focus on independent construction projects, ignored the renovation process of ecological engineering construction, due to lack of related theory as the guidance, engineering construction and renovation of land management after the actual ecological environment effects of doubt.This paper based on landscape ecology from the district land management scale of land management to study the content of the two aspects of ecological planning and evaluation. On, on the basis of predecessors’ research, summarizes the research situation at home and abroad, the application of landscape ecology in the aspect of land use for the study concluded that using the landscape ecology at present some of the more advanced and applicable research theory and methods of the regional scale, combining the theory of land reclamation work need for research. Has achieved the following results:1, based on landscape ecology, the study of the theory of the ecological planning of land regulation:The patch, corridor-matrix landscape planning model, divide the landscape ecological unit of land reclamation area, divided into cultivated land, garden land, forest land, roads, rivers, pits, ditches, settlement of several different landscape types.Study land management scales the landscape ecological system USES one of the commonly used method of spatial pattern analysis of landscape pattern index method, analysis and process of the pattern of land management system in the relationship; Selected the three kinds of landscape pattern index for the planning of the study area landscape pattern in the study area to the planning, specific chose landscape patch characteristics, landscape diversity index, gallery features three types.To the landscape pattern index screening, building the landscape pattern index system of land reclamation area, make a comprehensive analysis and research, and put forward corresponding planning design method and content. Specific chose the patch number, average patch area, patch density index, Shannon diversity index, evenness index, dominance index, average corridor width index, corridor density index, corridor connection degree index after 9 kinds of index on the planning of the landscape changes in expression, reflect the change of landscape ecology after each landscape situation and planning the consequences.2, Land management mainly consists of landscape ecological pattern analysis and evaluation of the ecological landscape ecological quality evaluation of two parts:(1).landscape ecological pattern analysisMethods of ecological planning land regulation is consistent first for the division of landscape unit.The use of landscape pattern index method to analyse and evaluate spatial pattern, landscape pattern index system construction of land management scales, the landscape ecological planning pattern change before and after data processing and analysis.(2).the landscape ecological quality evaluation:The index system of evaluation goals determine and establish.To determine the index weight.The comprehensive evaluation results.To sum up, in the land management under the guidance of the theory of landscape ecological construction, this paper for the future of land management of ecological planning and design methods, the means of evaluation and testing of the planning and design is reasonable, provides the scientific theoretical basis for reasonable. Hope to try to study land renovation project planning for the future has important guiding significance and reference, to alleviate the pressure of the population, resources and ecological environment at the same time as part of a little contribution...
