新疆宏观生态环境质量综合评价研究——以布尔津县为例

新疆地处中国西北典型干旱内陆区,生态环境比较恶劣,建立适合新疆的省区一级生态环境质量综合评价指标体系,将对科学、客观了解新疆乃至整个西北干旱区生态环境状况都具有十分重要的理论和实践意义。采用综合指数法,从降水量、植被指数、生态功能价值、土壤侵蚀、降尘量、悬浮物等6个方面选取指标,分别以景观单元和县市为评价单元,建立了简易合理、具可操作性的不同尺度的新疆生态环境质量评价指标体系,并确定了各指标的权值和相对的分级标准,为新疆生态环境现状的准确评价提供了可靠依据,对新疆社会经济的可持续发展和生态环境管理将起到积极作用。

The Xinjiang Macroscopic Ecological Environment Quality Synthetic Evaluation Research——Take Burqin County as the Example

Xinjiang is situated at file Chinese northwest model arid interior area, the ecological environment quite is bad, the establishment that suited Xinjiang＇s provincial capital area level ecological environment quality synthetic evaluation target system, to scientific, objectively understood Xinjiang and even the entire northwest arid area ecological environment condition all has tire extremely important theory and the practice significance. Using the synthesis exponential method, selecting the target from the precipitation, the vegetation index, the ecology function value, the soil erosion, the falling dust quantity, fire suspension and so on 6 aspects selects the target, respectively take the landscape unit and the county city as the appraisal unit, has established simple reasonable, the feasibility different criterion Xinjiang ecological environment quality appraisal target system, and had determined various targets weight and the relative graduation standard, have provided the reliable basis for the Xinjiang ecological environment present situation accurate appraisal, to the Xinjiang social economy sustainable development and the ecological environment management the positive role.
