土壤—作物资源多目标优化配置分析

本文提出一种多目标土壤—作物资源优化配置的数量化分析方法，并对江苏省东海县土壤资源进行优化配置。结果表明：白浆土、岭砂土、包浆土、紫砂土等岗岭低产土应稳定小麦面积，压缩玉米面积，优先发展春花生、大豆、水稻；洼地砂姜黑土、水稻土应发展小麦—水稻和小麦—玉米两熟制，并适时换茬；介于上述两类土壤间的潮棕壤亚类和潮土类应大力发展小麦—花生两熟制。

Soilcrop resources optimization scheme formultiple objectives

Soil resources optimization scheme for multiple objectives with quantitative method was proposed in this paper.By this method,the optimizing scheme of soilcrop in Donghai County,Jiangsu Province was studied.The optimizing results are stablizing the wheat planting area,reducing corn area and giving priority to the development of peanut,soybean,rice etc.in the hilly low yielding soils such as Bleached Beifiang Soils,Lithic Brown Soils,Peachic Soil,Sandy Purple Soils etc.;developping double cropping systems of wheatrice and wheatcorn as two crops of one year and adopting alternative culture at due time in lowland soils such as Shajiang Black Soils and Paddy Soils;and greatly extending wheatpeanut as double cropping system in the soils,such as Aguic Brown Earths and Fluvoaguic Soils
