1980—2015年伊犁盆地土地利用/覆被变化及驱动力研究

本文利用GIS相关技术，以 1980年、2000年、2010年与2015年新疆伊犁盆地Landsat-MSS、Landsat-TM/ETM遥感影像数据、气象数据与社会经济数据为主要数据源，分析并研究了伊犁盆地近35年的土地利用/覆被变化特征及其归因。结果显示:研究期间，变化最为显著的是草地，变化率为5.072%，共计减少2 801 km2，退化较为严重；其次是耕地，变化率是3.676%，共计增加2 030 km2，增加趋势明显；变化最不明显的是林地，变化率是0.045%。同时研究区内的半永久性冰川雪地面积出现了小幅度的降低，盐碱地、沼泽地、沙地出现了不同程度的增加，表明生态环境存在小幅度恶化现象，值得警示。当地的社会经济发展状况与自然条件共同塑造了本研究区的土地利用/覆被变化现状，其中社会经济因素是本地区土地覆被变化的主要推动因素。希望本文的研究结果能够为伊犁盆地生态环境建设提供一定的参考意义。

This paper is based on GIS technology, and takes Landsat-MSS, Landsat-TM/ETM remote sensing image data, meteorological data and social and economic data as the main data sources in 1980, 2000, 2010 and 2015 in the Yili basin, the land use/cover change near 35 years in study area was analyzed and researched. The results showed that during the study period, the most significant change was in grassland, with a change rate of 5.072%, a total decrease of 2,801 km2, a more serious degradation, followed by arable land, with a change rate of 3.676%, a total increase of 2,030 km2, an increase of obvious trend, and the least significant change was in forest land, with a change rate of 0.045%. At the same time, the semi-permanent glacier snow area in the study area showed a small reduction, saline land, marshland, sand land appeared to increase to varying degrees, indicating that the ecological environment has a small deterioration phenomenon, it is worth warning. The local socio-economic development and natural conditions together shape the land use/cover change status quo in the study area, in which the socio-economic factor sits as the main driving factor of land cover change in the area. It is hoped that the results of this paper can provide some reference significance for the ecological environment construction of Yili basin.
