从荒坡地新建果园１０多种作物间种模式中筛选出５种优化模式，分析和评价了各种模式对农业资源的利用及果树生长的影响和经济效益。
Northwest Guangxi is characterized for its natural resources deterioration, environment degradation and lagged economy. The Chinese government had decided to move poor people with lack of land and water resources in this region to a hilly region where there is rich uncultivated land so as to eliminate poverty and develop local economy. Chinese Academy of Sciences constructs the experiment zone of resettlement, which located in Huanjiang County, Guangxi province, to quest for a new way to enhance the efficiency of natural resources utilization and the poor's earning level. Years of research work indicates that intercorp pattern highly influences the natural resources utilization in the orchard. Several intercorp patterns are expounded in this paper. The author evaluates their influences on the utilization of agricultural resources and the growth of fruit tree. Five optimized intercorp patterns is put forward based on above analysis and it can be concluded in the end,that spring soybean_Autumn soybean pattern and peannt_Autumn soybean pattern are appropriate for wide spread in similar area;cayenne_tomato soybean pattern and potato_chinese cabbage pattern are suit for the construction of vegetable production base near the town centre of a county and rice_carrot pattern are fit for the early stage of the construction of experimental zone.
