| 摘 要： | 基于1985、2000、2017年3期土地利用遥感监测数据，利用土地利用转移矩阵、重心模型、生态环境质量指数等方法，对松嫩平原东部30年间土地利用转型时空变化特征及生态环境效应进行分析.结果表明：1985~2015年，松嫩平原东部地区土地利用以耕地和林地为主，分布界线清晰.土地利用强度持续增加，前期增加较快，后期趋缓.土地利用转型主要表现为农业生产用地持续增加，生态用地持续减少，建设用地小幅增加，前期变化剧烈，后期趋缓.土地利用转型方向较为稳定.重心转移轨迹变化较大，其中变化最大的是1985~2000年，水域的转移轨迹向西北方向偏移76.34 km.松嫩平原区域生态环境质量指数从1985年的0.395持续下降至2017年的0.361，生态环境质量持续恶化.2017年空间分布以中质量区和中低质量区为主，农业生产用地与草地、未利用地之间的相互转变是影响生态环境质量变化的主要因素.

| Abstract: | Based on the remote sensing monitoring data of land use in 1985, 2000 and 2017, the spatiotemporal variation characteristics and eco-environmental effects of land use transition in eastern Songnen Plain in the past 30 years are analyzed by means of land use transfer matrix, gravity center model and eco-environment quality index. The results show that the land use is mainly cultivated land and forest land with clear distribution boundary during 1985-2015. The land use intensity continues to increase, fast in early stage and slow in later. The main performances of land use transition involve continuous increase of agricultural land, continuous decrease of ecological land and slight increase of construction land, changing drastically in early stage and slowing down in later. The direction of land use transition is generally stable. The shift trajectory of transfer barycenter varies greatly, of which the largest change is during 1985-2000, with the transfer trajectory of water area shifting 76.34 km northwestward. The regional eco-environmental quality index of Songnen Plain continued to decline from 0.395 in 1985 to 0.361 in 2017, indicating the continuous deterioration of eco-environmental quality. In 2017, the spatial distribution is dominated by medium and low-medium quality areas. The mutual transition between agricultural land, grassland and unused land is the main influencing factor of ecological environment quality. |
