摘要
本文根据新疆棉花生产条件和棉区发展条件 ,提出了新疆棉区发展的“棉田优势度”、“棉田集中度”、“棉田潜力度”、“棉田规模度”、“棉田饱和度”、“棉花生产潜力”6个概念 ,设计了评价模型及其相应指标体系 ,进一步将全疆 6 0个产棉市县、10 0个产棉兵团农场分为超饱和制约型风险宜棉区、超饱和控制型风险宜棉区、未饱和潜力型最佳宜棉区、未饱和潜力型次佳宜棉区、饱和制约型不宜棉区和饱和制约型撤消棉区 6个发展类型 ,并对棉区发展规模潜力进行了预测 ,不仅为农业可持续发展和评价研究 。
Cotton is one of the economic crops with the most superiority in Xinjiang and cotton area of Xinjiang is one of the biggest three cotton areas in China.Cotton production and distribution will decided by many conditions and factors as bellow：heat、light、water、soil、plant diseases and insect pests and mixed weeds. The regional division of the cotton areas is according to the relative identical and similarity in geographical position、geomorphologic unit、natural factors、economic conditions and crop varieties.There are three big cotton regions：South、North and East of Xinjiang；The drainage division of the cotton areas rely on the integration and consistent of valley river and irrigating system on the basis of its regional division.There are eleven cotton valleys in Xinjiang；The suitability division of the cotton areas depends on six indexes:the degree of productive superiority、spatial assembling、increasing and scale potentiality、saturation and production capacity.There are sixty cotton cities、counties and one hundred cotton farms in Xinjiang，and they are divided into six development types:over-saturation controlled、over-saturation limited、unsaturation best 、unsaturation better、negative-saturation restricted、negative-saturation repealed. Under certain proportion of grain to cotton,the forecasting of cotton scale capacity has been made and per unit area yield of cotton is determined.Finally,the author put forward some countermeasures for the government in making decision on cotton production and arrangement.
