| 摘 要： | 本文应用遥感和地理信息系统相结合的方法,分析了吉林省湿地资源的空间分布及植被特征,并对近20年来吉林西部地区的湿地变化特征作了进一步的探讨。研究表明湿地资源空间分布不均匀,区域差异明显。吉林西部湿地面积减少趋势显著,其湿地面积减少了22.1%,年均变化率为1.1%。湿地资源保护和可持续利用已成为一项重要任务。 |

| Abstract: | Based on remote sensing and Geographical Information System technologies,the spatial distributionand the vegetationcharacters of the wetlands of Jilin Province have been analyzed.The results show that the wetlands are mainly distributed in the eastern and western parts of Jilin Province.The wetland area of six counties in the western part accountsfor 67.37% of the total area of wetland in Jilin Province.The area of wetland in Jilin Province decreased greatly from 1982 to 2002.Especially,the wetland area in the western partdecreased to 22.1%,so that theprotectionand sustained utilizationof wetland resources have become rigorous missions. |
