中文摘要: 利用精河流域1990、2011年TM-5影像数据,构建了精河流域反照率-植被指数特征空间下的荒漠化遥感监测模型。结果表明: 1990-2011年期间,研究区荒漠化总面积减少了3. 54 * 10~4 hm~2,占研究区国土总面积的3. 2%,但其中除了中度荒漠化面积以每年0. 82% 的速度减少外,极重度、重度和轻度则分别以每年0. 74%、0. 38%和0. 01%的速度在增加,极重度荒漠化的增长速度较为突出。由气候变化导致的荒漠化发展,近些年来正被政府的积极措施所部分抵消,但人口压力、水资源低效利用等人文因素,仍是未来荒漠化防治过程中需要克服的重点。
英文摘要: With the TM-5 remote sensing data in 1990 and 2011 OF Jinghe watershed,a method to monitor desertification was built based on the Albedo-NDVI scatter plot. The results showed that the total area of desertification was reduced by 3. 54 * 10~4 ha from 1990 to 2011 in the study area. Although the moderate desertification was reduced at the speed of 0. 82% per year, the highly severe desertification,severe desertification and mild desertification were increased at the speed of 0. 74%,0. 38% and 0. 01% per year respectively. The growth degree of highly severe desertification was still more prominent. Although the active steps which were taken by government were counterbalancing desertification caused by climate change in recent years,the reversion of desertification was slowed down by the population pressure,the inefficient utilization of water resources,and so on. These human factors were the unfavorable factors in combating desertification,which needed to be overcome in the prevention and control of desertification in Jinghe watershed in the future.
