Soil erosion, along with semiarid to arid climate, dissected topography and fragile ecological environment, makes land productivity very low and the livelihood of rural people even hard. In order to promote appropriate strategies for soil erosion control and small watershed agricultural development techniques, long-term research has been carried out by Beijing Forestry University sponsored by the China government since 1981,in a small watershed, Huangjiaercha, of Xiji County in Ningxia Hui Nationality Autonomous Prefecture. These efforts have resulted in identifying appropriate technologies in relation to resource level, these strategies could be extended to similar agro-ecological situations. Soil and water conservation practices adopted in the watershed revealed that with investment level and continuous adjustment, soil losses of small watershed could be reduced by 98%, apart from increasing crop yield and per capita net income by 526% and 566% respectively. The impact of soil erosion control measures and its benefits will be discussed in this paper.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学農学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/3674"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0370-4246"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250548"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学農学部学術報告"},{"subitem_1522650068558":"en","subitem_1522650091861":"The Science Bulletin of the Faculty of Agriculture.
