| 摘 要： | 辽宁省东部山区现有柞蚕场面积74．5万hm^2，由于近年来过度开发，管理粗放，造成土壤侵蚀加剧，生产力下降。为更好治理柞蚕场，了解掌握其土壤侵蚀程度和规律，结合全省土壤侵蚀研究，通过野外模拟降雨试验，着重对不同降雨、坡度、雨前土壤含水量和植被盖度条件下柞蚕场的土壤侵规律，进行了较为系统的研究，得出4因子与土壤侵蚀之关系，为有的放矢地采取相应的治理管护措施，提供了一套科学的基础依据。

| Abstract: | The area of tussah silkworm nursery in mountain area of eastern Liaoning is about 745 000 hm2,owing to overexploitation, extensive management in recent years,the soil erosion has become intensified,the productivity declined.Combining soil erosion study of whole province,through the experiment of field simulated rainfall,the law of soil erosion in tussah silkworm nursery is studied systematically under the conditions of different rainfall,slopes,soil moisture before rainfall and percentage of vegetation in order to manage the tussah silkworm nursery well,to understand and master its situation and law of soil erosion.Therefore,the relation between four factors and soil erosion is obtained.That provide a set of scientific basis for the corresponding measure of control and management. |
