| 摘 要： | 利用遥感、地理信息系统技术方法,精确解译顺庆区2000年与2007年两期Landsat-TM遥感影像,获得该地区土地利用/覆被的矢量图及定量统计数据,综合运用动态指标分析了LUCC特征。研究结果表明：该地区的耕地、林地和建设用地是LUCC的核心类型,三者面积之和超过研究区总面积的90%。7年间土地利用/覆被变化速度较快,耕地面积逐年减少,林地和建设用地面积显著增加,草地、水域则有少许减少。这些分析结果为查明该区土地利用及变化情况,揭示其中存在的问题,相关部门制定国土规划提供了科学依据。

| Abstract: | RS and GIS were applied to interpret precisely Landsat-TM remote sensing image of shunqing region in 2000 and 2007.Quantitative statistic and phasor diagram on land use/cover had been worked out,and dynamic characteristics of LUCC were analyzed.Experimental results show that cropland,forest and Construction land were main types of LUCC in this region,the total area of the three accounting for more than 90 percent of the whole area.In 7 years,the cropland area decreased,forest land and construction land increased,grass and water area reduced a litter.These analysis could provide a scientific basis for the relevant departments to know about the situation of the region and make a better use of the land resources. |
