不同蚕区蚕桑生产与气候因子关系的研究

RELATIONSHIP BETWEEN SERICULTURAL PRODUCTION IN DIFFERENT AREAS OF ANHUI PROVINCE AND CLIMETE FACTORS

本文采用灰色系统理论和方法，研究了安徽省各蚕区的蚕桑生产与气候因子的变化规律，通过关联分析，研究了影响各蚕区的气候因子，建立了年茧量及亩桑产茧量的灰色静动态模型．研究结果表明，气温、降水、日照是影响各蚕区蚕桑生产的主要因子，但由于不同蚕区气候条件的差异，各蚕区的重点气候因子又各不相同；利用气候因子所建立的方程，与年茧量、亩桑产茧量的实际值及变化规律有很好的拟合度．

Relations between Sericultural production in different areas of Auhui Province and climate factors were studied with gray systematic theory and method.The climate factors which affects mony sericultural regions were dealt with the method of relative analysis and the gray model about annual cocoon production output,and cocoon production a per mulberry treesn were established.It was shown that the atmospheric temperture,rainfall and sunshine were main factors of afiecting sericultural production.But the main climate factors in different sericultural areas were also significant due to their climate condition.The annual theoretical output of cocoon predicted with the mothods fitted in with the practical productions very well.
