黑河中游地区生态环境演变及其驱动因子分析

摘要

为分析黑河中游地区生态环境变化趋势及其成因机制,选取2000年和2011年研究区遥感影像数据资料,建立土地利用类型转移矩阵并进行对比分析,结果表明:2000-2011年,黑河中游地区生态环境演变趋势主要为未利用地向耕地转化,其他各种土地利用类型间转换也比较频繁;生态环境演变是自然因素与人为因素共同作用的结果,其中人为因素占主导地位.%In order to analyze Heihe River middle reaches area of the ecological environment change trend and its formation mechanism,this paper selected the 2000 and 2011 study area remote sensing image data to establish the land use type matrix for remote sensing image data a-nalysis. The results show that:a)in 2000-2011,in the middle reaches of Heihe River,the mainly evolution trend of the ecological environ-ment is from the unused land to cultivated land,other types of land use conversion is also frequently;b)the main factors which the trend of the ecological environment are the results of the interaction between the natural factors and human factors,among them,human factor occu-pies the mainly position.
