摘要:
为促进区域土地资源的科学管理和可持续发展，根据遥感影像解译的喀什噶尔河流域2000-2015年土地利用/覆被类型面积数据，对比分析了流域土地利用/覆被的变化，探讨了流域土地利用/覆被变化对区域生态环境可能产生的影响。结果表明：在2000-2015年，喀什噶尔河流域不同土地利用/覆被类型的面积发生明显变化。其中，耕地面积增幅高达53%，居工用地面积增幅高达68%，水域面积增加了17%，未利用地面积增幅约3%，天然林面积减少幅度高达33%，冰川和积雪面积减少55%。流域不同土地利用/覆被类型空间分布格局未变。流域存在的与土地利用相关的生态问题有：一是土地利用类型面积变化显著，土壤盐渍化严重；二是灌溉面积过大，农业灌溉用水利用效率低，生产生态用水矛盾突出；三是流域下游因多年断流，沿河岸分布的以胡杨为优势建群种的荒漠河岸林生态系统退化显著，胡杨林下土地沙化明显。
Abstract:
In order to promote the scientific management and sustainable development of regional land resources,based on the area data of land use/cover types in Kashgar River Basin from 2000 to 2015 interpreted by remote sensing images,the land use / cover change in the basin was compared and analyzed,and the possible impact of land use/cover change on regional ecological environment was discussed.The results showed that，from 2000 to 2015,the area of different land use/cover types in Kashgar River Basin changed significantly.Among them,cultivated land increased by 53%,residential land increased by 68%,water area increased by 17%,unused land increased by 3%,natural forest area decreased by 33%,and glacier and snow area decreased by 55%.The spatial distribution pattern of different land use/cover types remained unchanged.The ecological problems related to land use in the basin were as follows: first,the area of land use type had changed significantly and soil salinization was serious; second,the irrigation area was too large,the agricultural irrigation water use efficiency was low,and the contradiction of production ecological water use was prominent; third,the desert riparian forest ecosystem with Populus euphratica as the dominant species distributed along the river bank in the lower reaches of the basin had been degraded significantly due to the lack of water for many years,and the soil desertification under Populus euphratica forest was obvious.
