| 摘 要： | 采用1988年和2002年两期TM遥感图像,利用遥感和地理信息系统技术提取宝应县这一长江中下游典型湖荡区的湿地资源信息,通过数量分析和转移矩阵分析从总量变化、类型结构、变化速率、湿地类型转移百分比和转移面积等多方面揭示了宝应县湿地资源的动态变化情况。结果表明:14年来湿地面积显著减少,结构发生了重大调整,以原来的滩地和稻田为主转变为以稻田和养殖水面为主。各类型的土地向稻田和养殖水面转移最为明显,其中滩地向稻田和养殖水面的转移面积最大。

| Abstract: | Based on the TM images of 1988 and 2002, this paper uses the technologies of Remote Sensing and geographic information systems to obtain the wetland resources of Baoying County, a typical marsh region of the middle and lower reaches of Changjiang, and reveals the dynamic changes of the wetland resources from the perspectives of total change, type structure, change rate, and the transfer percentage and area through the quantitative analysis and transfer matrix analysis. The results indicate that in the past ... |
