An environ economic harmonized inexact system programming for agricultural forestry landuse in the lake Erhai basin
洱海流域环境经济相协调的农林土地利用不确定性系统规划

An interval numbers optimization model was applied to study the Lake Erhai Basin in Dali, Yunnan Province. It is indicated that the current landuse pattern in the lake basin need to be improved, and the detailed programs are different for sub areas. To achieve a reasonable and applicable program, the decision maker can integrate the solutions of the model with his experience and other relevant information. The generated program can guarantee a maximized economic output within the limit of non point source pollution contribution.
