阿图什市“十五”期间土地利用变化及分析

Analysis on Land Using Change in Atushi during the 10th Five-Year Plan

利用2001—2005年的遥感影像数据(覆盖范围主要是克孜勒苏柯尔克孜自治州行政辖区内的阿图什市),通过统计2001—2005年土地利用数据,分析了该市近五年土地利用/覆盖的时空变化规律,并进而探究了导致该变化发生的自然、人文驱动因素。结果表明:在2001—2005年,该区域林地和草地面积增加,耕地面积减少,土地沙化和盐碱化现象得到遏制。探其原因主要是由社会、经济等人文因素造成,而包括气候波动在内的自然条件只是土地利用变化的背景条件。

Using RS data covered with atushi city in 2001 -- 2005, land using data and temporal and spaeial rules of land using/ coveting were analysed for studying driving factors of environment change in the paper. The results showed the forest and grass area of typical region increased,but infield area reduced during this five years. Land desertification had kept within limits, which resulted in society and economy factors. Nature conditions including fluetuant climate was only background condition of land using change.
