The Research On Coordinating Land Use And Ecological Environment

Land use change is generally reflected in the land use way change,and different regions of the land use change in the number,intensity,structure and trends,and other aspects,there are many differences,environmental changes in the region will have a direct or indirect impact, that is believed the main reasons to be caused changes in the ecological environment.Therefore the improvement of the ecological environment,we must strengthen land management,rational use of land resources,land use to avoid causing ecological damage to the environment and improving the ecological environment,the land resources must be an important element of the ecological environment protection;improvement of the ecological environment,the reasonable ecological construction land should be obtain the safeguard. Coordination of land use and construction of the ecological environment in order to achieve the sustainable development of land use central link.The core problemsmustbe solved in the nearest revision ofcomprehensive land use planning are the coordination of the relationship among population, resource, environment and development and the assurance of the continuous development of resource,economy and society.This paper Puxian as an example,the use of land ecology and ecological economics theory,the relation of human and land and the idea of sustainable development,on the basis of in-depth surveys and extensive collection of Puxian ecological environment and natural resources information to analysis the question which exists to the land ecological construction,Puxian land use study on the environment be taken into consideration,emphatically from strategic overall situation and partial,the strategic overall situation and the strategic environment's interaction,restricts mutually in relations,generalized analysis land ecological construction characteristic,and vertical and horizontal contrast,find favorable conditions and constraints,thus proposed that the science reasonable developmental strategy,develops for the economic society provides the land use the plan and the policy suggestion;to Puxian ecological environment supporting capacity research foundation.The annual ecological carrying capacity and ecological footprint of Puxian in 2005 are calculated by the emergy&footprint model.Dynamic analysis and assessment of the present condition of the regional ecological security are accomplished by calculating the per capita ecological deficit/surplus.In investigates Puxian land ecological environment condition in the foundation,has analyzed the land structure and the scale,the infrastructural facilities,the land development reorganizes,the significant ecological environment construction project to the ecological environment influence;Finally by the research base,in response to Puxian actual land use and construction of the ecological environment,proposed the ecology improvement principle as well as the ecological construction land arrangement suggestion.
