摘要
采用地理信息系统软件对1980、1990、2000年中国县域棉花生产数据进行处理,生成棉花种植空间分布差异地图并对之进行分析。分析结果表明,1980～1990年,中国棉花种植空间迅速缩减地区是鄂南、鄂中、湘北、陕西中部、晋西棉区、冀西南棉区以及江苏东部部分地区,种植空间迅速扩展的地区是鲁西北、鲁西南、冀东南和豫南等地区;同时,新疆棉区以巴楚县为核心的南疆等地区种植面积增长迅速;1990～2000年,变异的最大特点是新疆棉花生产的崛起和山东、河北棉花生产的萎缩。引起上述变化的原因是由于经济、政策、技术及自然以等因素发生变化的结果。
In this paper, firstly, the data of cotton production in some provinces of China during the periods of 1980～1990 and of 1990～2000 respectively are processed, and the maps of spatial distribution and variation of cotton production are charted and analyzed by using geographic information system. The results show that, during the period of 1980～1990, the cotton growing areas were reduced in the southern and central parts of Hubei Province, the north Hunan Province, the central part of Shaanxi Province, west Shanxi Province, the southwest Hebei Province and some regions of east Jiangsu Province, whereas the cotton growing areas were rapidly enlarged in south Xinjiang, especially in Bachu county; during the period of 1990～2000, cotton production was greatly developed in Xinjiang, but it was shrunk in Shandong and Hebei provinces. These changes were caused by many kinds of factors including the economic, policy, technical and natural factors.
