本文探讨了农业景观规划的多准则分析方法。案例研究是在Cianjur流域，西爪哇，印度尼西亚，近年来经历了土壤侵蚀问题。规划过程包括侵蚀危害、土地适宜性和经济可行性分析。土地资源信息是从地形图、大地卫星TM图像、土壤图和气候数据中发展起来的一个地理信息系统数据库。利用这些数据，通用土壤流失方程被应用于侵蚀危险性分析。在土地适宜性分析中，以联合国粮农组织的土地适宜性评价方法为基础，比较了各地区植物对土地的需求和土地资源特征。在经济可行性分析中使用了每种作物的生产成本概况和价格数据。根据这三项分析的综合结果，对拟议的农业生态土地利用进行了规划，根据这些规划，土地利用类型不会造成超过可容忍的土壤流失，就土地资源质量而言至少是勉强适合的，并且在经济上是可行的。与目前的农业用地相比，拟议的农业生态用地将减少该地区约75%的土壤流失，而农业生产的总利润仅减少3.1%。
This paper addresses a multi-criteria analysis approach to agricultural landscape planning. The case study was conducted in the Cianjur watershed, West Java, Indonesia, which has experienced soil erosion problems in recent years. The planning process consists of erosion hazard, land suitability, and economic feasibility analyses. Land resource information was developed as a GIS database from topographic maps, Landsat TM images, soil maps, and climatic data. Using these data, the universal soil loss equation was applied to erosion hazard analysis. In land suitability analysis, the land requirement of plants, and land resources characteristics were compared on the basis of Food and Agriculture Organization's land suitability evaluation methods. Production cost profiles and price data for each crop were used in the economic feasibility analysis. On the basis of the integrated results of the three analyses, proposed agro-ecological land-use was planned under which the land-utilization types would not cause more than tolerable soil loss, would be at least marginally suitable with regard to land resources quality, and would be economically feasible. When compared with current agricultural land-use, the proposed agro-ecological land-use would reduce total soil loss in the area by about 75%, with a reduction in total profit from agricultural production of just 3.1%.
