Study On The Planning And Design In Land Consolidation Projects Based On Landscape Ecology

Integrating external and internal extension, Land consolidation can effectively protect the farmland and lessen the conflict between land and people's requirement. With sustainable land consolidation gaining momentum, the traditional planning and design which target at increasing the quality and quantity of farmland cannot meet the demands of protecting the environment and sustainably using the land. Landscape ecology, however, can serve as the guideline of land consolidation. By which, the agricultural landscape ecosystems of project areas should be restructured and these areas can be landscape eco-constructed. In this way, increased productivity of creatures in the system, and enhanced ecological environment and cultural service can be foreseen. This thesis can be of some reference value for the theoretical research and practice in sustainable land consolidation of our country.This thesis constructs theoretical analysis framework based on the key elements of landscape ecology, i.e., landscape structure, landscape function and landscape dynamic. Having cleaned up the history of landscape ecology and its practice at home and abroad, this thesis sheds light on the correlation between structure and function, principle of scale analysis and human dominance in landscape evolution. This thesis divides the units of project areas by applying the pattern of patch-corridor-matrix. This thesis tries to explore the objectives, principles and contents of the planning and design of landscape ecology. The ecological significance of landscape pattern index helps to build up index analysis system suitable for the scale of land consolidation. This thesis proposes some measures of landscape ecology planning and design in the project areas. This thesis also contrasts analysis of the suggested and the traditional planning and design. In the last, the projects carried out in two towns, Xiaosi included, of Caidian district of Wuhan is set as examples of landscape ecology planning and design.The approach to studying land consolidation at the footing of landscape ecology offers a new perspective in this realm. The theories and methods are put forward for the first time and meanwhile the research of landscape ecology is extended into the microcosmic field.The measures include:(1) preserving the forms of landscapes of ecological importance and increasing landscape heterogeneity and biodiversity; (2) reasonably planning landscape forms, adjusting landscape structures, decreasing landscape fragmentation index and optimizing biological environment; (3) facilitating the establishment of landscape patch and corridor and ensuring unimpeded circulation of flow of species, creatures and energy.
