| 中文摘要 | 丽江县位于云南省西北部,金沙江的南岸。境内有着一定的水土流失条件,因而开展水土保持,不仅有益于当地生产的发展,而且对维护万里长江的生态平衡亦具有一定的作用。 本文在实地调查基础上,仅就丽江县水土流失的条件、类型、现状与特点,以及水土保持和土地资源合理利用的关系发表一点粗浅的见识。 |
| 英文摘要 | Li Jiang County is located at the south bank of Jinsha River in the Westnorth Yunnan Province.Total area is more than 6200km2. The area of siol erosion occupys 17km2 approximately.In this region there; are some conditions for soil erosion, e. g. the material of earth surface is loose, the topography is incised to be broken, the height differance is more great between the mountain ranges and the gully valleies, the precipition is abundant and concentrative, as well as the vegetation is broken.The annual erosion in Li Jiang County is up to more that 620000t, which is equal to weight of surface soil in 2.7km2 i. e. more that 4000mu. Such being the case, the losses of soil nutrients are 9000t for elements N, P, K of great quantity, and more than 1000t for micro-nutrients Zn, Cu, Mn during a year approximatively.Characteristics of soil erosion in Li Jiang County are there is a positive correlation between soil erosion and precipitition. At same time, there is a gradually increasing tendency for soil erosion, this is an attentive question.Finally, the reasonable utilization questions of land resources are discussed.Based on suitable measures to local conditions the suggestions for the reasonable development and utilization of land resources are proposed in accordance with the characteristics in various districts. |
