新疆则克台堰塞湖地区生态环境质量变化分析

Analysis of Ecological Environment Quality Change in Zeketai Damned Lake Area, Xinjiang

利用遥感影像,结合地形、气象及土壤质量等数据,基于综合指数法,分析了2000—2014年则克台堰塞湖地区生态环境质量及其变化情况。结果表明:(1)近15年,则克台堰塞湖地区生态环境质量一般,总体呈下降趋势,生态环境质量下降区域随时间由研究区东北部向西南部迁移;(2)滑坡泥石流等地质灾害为该地区生态环境质量变差的主要原因;(3)该地区生态环境在遭到破坏后,通过自我调节或可在3年内得到明显改善。本文依据则克台堰塞湖地区生态环境背景建立了适用于当地的生态环境质量评价指标体系,为生态环境修复及防灾救灾提供理论依据。

Based on the Remote Sensing images,combined with the data of topography,meteorology and soil quality,the ecological environment quality and its changes of Zeketai dammed lake area from 2000 to 2014 year were analyzed using the comprehensive index method.The results show:(1)In the last 15 years,the main type of ecological environment quality of Zeketai dammed lake area was“general”.But the ecological environment quality has showed a trend of reduction.The degeneration regions had shifted from the northeast to the southwest of the study area.(2)The landslide debris flow and other geological disasters were the main driving factors for the deterioration of the ecological environment quality in this area.(3)The ecological environment may has been greatly improved in 3 years after the destruction.Based on the ecological environment background of Zeketai dammed lake area,the ecological environment quality evaluation index system was established to provide the theoretical basis for the ecological environment restoration and disaster prevention and relief.
