| 摘 要： | 应用遥感技术和定点调查相结合的方法对钱塘江流域水土流失及其动态进行分析．钱塘江流域省内水土流失量占全省总流失量的４７．６６％．钱塘江中上游的金衢地区是水土流失较严重地区，面租达３９５５ｋｍ２，占该地区山地面积的２３．２５％，衢州市近１０年（１９８１～１９９０年）间统计，水土流失面积由原来的１５８６ｋｍ２增加到２６７５ｋｍ２，扩大６８、６６％；以经济林为主的常山县开发过程中强调水土保持措施，但流失面积仍扩大４７、３８％；．以用材林为主的开化县水土流失有急剧上升的趋势。文章讨论了钱塘江中上游近期水土流失的特点并提出综合治理的建议．

| Abstract: | By remote sensing technique and spot investigation,analysis on water and soil erosion character and dynamics of Qiantang River basin showed that water and soil erosion quantity of Qiantang River basin took 47.66% of the total of Zhejiang provuince.Jin-Qu region,the upper and middle reaches had erosion area of 3 955km2,Statistics of Quzhou city in the recent ten years showed that water and soil erosion area increased from 1 586km2 to 2 675km2,y 68.66%.Changshan county had emphasis on taking water and soil conservation measures during exploitation or economic forest,but erosion area increased by 47.38%.Kaihua county also had tendency of increasing erosion area.Discussions were made on water and soil erosion characters of upper and middle reaches of Qiantang river in the recent Period and comprehensive ways were proposed. |
