基于遥感的库尔勒地区生态环境质量评价及成因分析

基于遥感的库尔勒地区生态环境质量评价及成因分析摘要：

库尔勒地区是世界上最大的干旱沙漠--塔克拉玛干沙漠南缘的重要区域，其生态环境质量的优劣呈现的综合性及系统性特点。基于遥感技术，本文利用2000~2015年间LandsatTM/ETM+遥感影像数据，结合GIS空间分析方法与生态环境质量评价指标体系，探讨了库尔勒地区生态环境质量的时空演变及其成因分析。主要研究结论如下：首先，库尔勒地区生态环境质量总体呈现“先好后差再好”的时空演变特征，2000~2010年间质量较好、2010~2015年间质量有所恶化。其次，影响库尔勒地区生态环境质量的因素较为复杂，涉及土壤侵蚀、生态系统结构破坏、气候变化等多个方面，其中以经济发展对生态环境的影响最为突出。最后，为改善库尔勒地区生态环境质量及其可持续发展，本文提出了一系列可行性建议，包括加强政策引导，优化土地利用结构，加大生态保护力度等。
