Ecosystem Health Assessment In The Tarim River Watershed

Along with the continual aggravation of the human living environment and generation of continuous strategy viewpoint, Creating the study of ecosystem health. Watershed is an independent topographic unit that has ecological integrality, As a comprehensive and integrated social, economic and natural ecosystem, it can offer many services.The aim to study watershed ecosystem health assessment is to manage and to recover ecosystem, to realize sustainable development of economy and ecology in watershed. It is very important for the improving of all people's living level and to keep the stability of xinjiang and china.In this article, Selecting the middle part in Tarim river as the study area for the evaluation of watershed ecosystem health, Using the remote sensing imagines in 2000, the hydrology datum and statistical datum in 2000, Building the evaluation index body, assessing the study area's health condition, Do detailed analysis From there part that is water resource, the ecosystem's tissue and structure, society and economy, The study conclusion can be referenced by people who manage watershed ecology and draw up policy .1. Detailed study content as follows:1) Summarizing the study of ecosystem health's expound and development, the study's theory of ecosystem health, assessed method and study criterion for the assessment of ecosystem health.2) Busied on the theory of ecosystem health, combined the watershed ecosystem's structure and function, from the viewpoint of comprehensive and integrated social, economic and natural ecosystem to study the assessment of watershed ecosystem, In all article, filled the viewpoint of synthetic assessment for watershed ecosystem health.3) With PSR (press-state-reflection) conception frame, to select corresponding index from human's interaction, ecosystem's structure and function and sciatic-economy. Designed assessment system for ecosystem health in Tarim river watershed4) Using remote sensing and GIS technique to get ecosystem's datum, join with hydrology datum and statistical datum to calculate assessment index, do a synthetic assessment and a corresponding analysis for the health of watershed ecosystem.2. Detailed conclusion as follows:1) In study area, Water resource condition is bad, ecosystem's structure and function is normal, society-economy is well now, we get a conclusion by synthetic assessment that ecosystem's health condition is normal in watershed.2) To say For Tarim river watershed which locates in northwest arid area, the exploitation and usage of water resource is decisive to realize it's sustainable development, it is necessary to...
