Barley (rape or green manure) -rice -rice, Wheat-rice and Wheat-cotton. cropping systems have been practised for a long time in the suburbs of Shaghai. Recently a new cropping system, Combined grain with forage cropping designed, Was compared with those cropping systems. The results showed that combined grain with forage and barley-rice-rice cropping systems have much advantage than the others in ecological benefit (efficient of energy and matter discharge) Social effects economic efficient and soil improvement and so on. On the basis of cropping pattern with rice and wheat (or barley) as the main crops, We may adjust rate of barley-rice or wheat-rice cropping system; reduce area of cotton crop by degree; develop special economic crops suitably such as medicinal herbs and spice crops; extend combined grain with forage cropping system vigorously for promoting the development of animal husbandry; set up pluralistic and compound structure of agriculture and realize a good circulation of agricultural ecosystem in the suburbs of shanghai.
上海郊区现行的麦(油、肥)-稻-稻、麦-稻、麦-棉种植制和我们根据上海大城市郊区的特点而设计的粮饲结合种植制,从生态效益(能流效率和物流效率)、社会效益、经济效益及土壤性质变化等几个方面的综合研究评价结果看,粮饲结合种植制和麦-稻-稻三熟制比麦-稻、麦-棉及其他种植制度有着明显的优越性。因此,上海郊区应该在坚持以水稻和麦类为主体作物布局的基础上,慎重调整麦-稻-稻和麦-稻之间的比例,逐步压缩棉花的种植面积,适当发展药材、香料等经济作物,大力推广粮饲结合种植制,促进多种畜牧业的发展,建立多元多层次的复合农业结构,实现农业生态系统的良性循环。

The economic effect of distributional adjustment of cotton fields in China was at its best during the northward move in 1981～1989 and at its worst during the southward move in 1961～1980. Distributional index of cotton fields is an index for measuring economic effect of yield increase per ha resulting from distrtibution of cotton fields in China. Based on the tendency of spatial distribution of distributional index of cotton fields in China, locational directions for adjustment of distribution of cotton fields are as follows:1. To expand the cotton-planting areas in the plains of North China lower reaches of Wei-Fen Rivers and Xinjiang.2. To reduce the cotton-producing scale in the south and north mountain areas of China.3. To condense the cotton fields in the south plains of the lower reaches of the Yangtze River.
