Spatial Structure Of Land Use And Ecosystem Function Of Relevance

In recent years, the land utilization received to the environment and the ecology function in the global environment change research area takes seriously, the related land utilization change's research project were getting more and more, how will the land utilization change in the future, when was one of present land utilization change research core scientific questions. May relates closely through the land utilization spatial structure analysis the land utilization spatial characteristic and the time process, thus may analyze the land utilization well the space and time evolution rule, but the land utilization spatial structure's change will further cause the ecosystem and the environment, between system interior various subsystems as well as various essential factors the interaction, the mutual influence, will thus cause the ecosystem function change. Therefore strengthens the land utilization spatial structure and the development change research has the important theory significance regarding the ecosystem function research.This article in analyzes in the domestic and foreign land utilization spatial structure rationale, proposed the land utilization spatial structure's concept, the absorption land utilization dynamic degree and the land utilization degree space and time model takes this research the rationale and the research technique. In the ecosystem function aspect, has discussed the ecosystem function composition structure, the functional analysis and the indicator system. Take the land arrangements as the example, studies project area land utilization spatial structure the change, as well as around land arrangements ecosystem function influence, discussion land utilization spatial structure and ecosystem function relatedness analysis.This article studies the primary coverage is as follows:The first part is an introduction, mainly elaborated the paper research background, the domestic and foreign research present situation, the research technique and the technical route.The second part for land utilization spatial structure the theory, first discusses the land utilization spatial structure the connotation, carries on the analysis to the land utilization spatial structure change's driving influence, then unifies in the foundation which the domestic and foreign scholars study to propose the land utilization spatial structure indicator system.The third part for the ecosystem function research, on the Earth the ecosystem is an open irreversible dynamic system, the system and the environment, between system interior each subsystem as well as various essential factors the interaction, the mutual influence, through the circulation of materials, the energy flow, the communication maintained in quite long time system's balanced. Has established the ecosystem function indicator system in this from two aspects, the ecosystem biomass reckoning and the ecosystem function carbon stores up the quantity the estimateThe fourth part is the empirical study, and so on two native soil reorganizes the project take state investment Hubei Province Anlu XinZha as the example, the utilization land utilization dynamic degree model and the land utilization degree space and time evolution model, analyzes around project area land arrangements the land utilization spatial structure change, and obtains the spatial structure change result.Land arrangements' implementation has simultaneously caused the ecosystem function change, this article stores up the quantitative change from the ecosystem biomass production change and the carbon cycle to analyze around project area land arrangements to the ecosystem function influence. Contrasts through project area land arrangements around, project area ecosystem biomass obviously increases, before the carbon stores up the quantity also to reorganize increases, the ecosystem function achieves one kind of dynamical equilibrium finally.The fifth part is a conclusion. Summarized the article main achievement and the conclusion, and aims at the insufficiency which in the research exists, had pointed out further studies direction.
