棉纤维综合品质地域分异评价系统的构建

Construction of the Integrated Cotton Fiber Quality Regional Distribution and Appraisal System

为了预测棉纤维综合品质,对棉纤维综合品质地域分异进行科学评价,以ESRI公司的MapOb-jects(MO)为开发平台,Visual Basic 6.0为开发语言,基于棉纤维综合品质模型,研制了棉纤维综合品质地域分异评价系统。该系统实现了对棉纤维综合品质地域分异规律的分析和预测,并可对黄河流域棉区和长江流域棉区224个棉花主栽县(市)站的气象因子数据库的维护与查询;实现了计算和预测各站点当年和下一年主栽棉花品种的棉纤维长度、比强度、麦克隆值和棉纤维综合品质,并自动生成专题图。以山东省为例,对棉纤维综合品质地域分异进行了评价。运行结果表明:(1)系统操作简单,运行可靠;(2)准确、直观地实现预测结果的空间表达;(3)实现对任意站点的评价,系统通用性与灵活性较强。此系统为国内首次开发,实现了黄河流域棉区和长江流域棉区棉纤维综合品质的预测和地域分异分析,为保障棉花区域经济可持续发展提供科学依据。

In order to predict and access the integrated cotton fiber quality and their spatial distribution, taking MapObjects as investigative platform, using Visual Basic6.0, then based on model of an integrated fiber quality index （IFQI）, the regional distribution and appraisal System of IFQI is developed. It can analy- sis and estimate cotton fiber qualities and their spatial interpolation. In the same time, meteorology factor database of 224 cotton lords in the Yellow River reaches and the Changjiang River reaches can be modified and inquired; then calculate and predict each station for that year and next year a lord to cotton fiber length, strength, micronaire and integrated fiber quality, and automatically make thematic map. The system takes province in Shandong as an example, evaluating regional difference of cotton fiber qualities. The movement expresses as a result： （1）System operation simple, running reliably; （2） Estimating accurately the space expression of result; （3） The appraisal system is practical and flexible. This system firstly developed in China, can be calculated and evaluated the Yellow River and Changjiang River cotton qualities for area distribution, in order to provide science basis for economy sustainable development of in the cotton district .
