摘要:
利用Landsat遥感数据解译得到的四期土地利用/覆被变化遥感数据（1972年、1990年、1998年、2011年）结合流域近40 a气温、降水量、径流量等气象水文数据，通过景观格局分析与统计学方法研究了近40 a典型山盆—绿洲—荒漠（MODS）耦合系统——新疆艾比湖保护区LUCC演化及其驱动力分析。结果表明：（1）近40 a研究区景观类型格局的空间转移情况变化明显，且各景观类型间的面积转换频繁。（2）40 a内斑块数量呈现先增后减的趋势，景观的异质性程度、Shannon多样性指数、Shannon均匀度指数都呈现出先减后增的趋势。（3）在影响研究区景观格局演变的自然驱动因子中，自然因素中年均、月均降水量的变化对LUCC的影响不明显，人为因素是驱动LUCC变化的重要因素。
Abstract:
This paper took Ebinur Lake of Xinjiang, a typical MODS background area of north China, as an example to investigate the driving forces on LUCC based on four land-use data (1972, 1990, 1998 and 2011) which were obtained from interpretation of Landsat images. Distance average analysis was adopted for finding characteristics of the interaction by combining with meteorological hydrological data such as temperature, precipitation and runoff. Firstly, it is obviously that the pattern of the study area landscape type changed and the area of conversion between different landscape types changed frequently in 40 years. Secondly, the landscape types first increased then reduced during 40 years, while the Shannon diversity index and the Shannon evenness index both first reduced then increased. Thirdly, with the regression analysis of meteorological and hydrological data for the watershed, the annual runoff of Ebinur Lake showed little change, which appeared an upward trend and a positive response to rainfall runoff. The land use/cover change could regulate the runoff significantly. The results show the direction of diversification of study area landscape. Human factor is one of the significant factors that influence the landscape types.
