Land Consolidation Project Of Landscape Ecological Evaluation In Tongshan

In order to improve the efficiency and the comprehensive production potential of land use, when the land consolidation began in2001, the country vigorously promoting the work of land arrangement. Land consolidation is a complex project, it contain ditch, cropland, road, village comprehensive arrangement and optimization, in the process the soil, vegetation, water resources, ecological system and environmental factors will suffer directly or indirectly harmful or beneficial influence.Farmland development may cause severe impact on the nature and the ecological landscape. The homogenization, fragmentation, and the landscape environment and ecosystem, which brought by farmland development is a long-term in the farmland consolidation we must face, these effects plays an important role on the land ecological environmental impacts and sustainable land utilization. Because Land consolidation will cause the landscape patch, corridor, matrix changed significantly, so the research is usually employed to reflect the changes of landscape structure landscape index of unit land consolidation ecological effect.Landscape ecological evaluation as a tool effects on raise the production potential of land, realize land sustainable development is important, so ecological landscape evaluation as a measure in the success or failure of an important criterion of land consolidation, is important practical significance.This paper selects Hubei province Tongshan land consolidation project as represented,analysis plaque, corridor, matrix to study the land before the later study of land consolidation project after the implementation of the project area landscape ecological effects, research shows:(1) The land use types distribute landscape fragmentation degree. Farmland as the study area the main types of land use, land consolidation, diversity and evenness decreased. Landscape fragmentation decreased.(2) The project area corridor main types of canals and roads. Project area before corridor network developed, after land consolidation project area road network has greatly improved. Structural feature index to raise shows after finishing the road ditch, increasing in complexity, contribute to the energy flow, species or species migration.(3) By selecting the landscape diversity, landscape fragmentation, landscape aggregation, corridor density, plaque accessibility, corridor network complexity six evaluation factor evaluation system is set up on the project land consolidation landscape ecological effect evaluation, the results showed that after the implementation of land consolidation project area in a certain landscape ecological effects the degree of improvement. Put forward land consolidation landscape ecological design...
