为充分认识新疆棉花秸秆资源的经济价值与开发潜力,文中选取修正后的草谷比对新疆棉花秸秆资源量进行全面系统的估算,选用Arc GIS软件分析棉花秸秆资源的区域分布特点,运用DPS软件结合因子分析与聚类分析方法对棉花秸秆资源进行综合评价。结果表明:1)新疆棉花秸秆资源量随棉花产量的变化呈波动增长,2013年新疆棉花产量为2.06×10~6t,可收集棉花秸秆资源量约为1.68×10~7t,若将2013年新疆棉花秸秆资源全部能源化利用,则相当于节省约9.1×10~6t标准煤;2)新疆棉花秸秆资源总量由南向北呈递减趋势,南疆、北疆、东疆棉花秸秆资源量分别占全疆总量的65.75%、30.97%、3.28%;资源丰度呈片状分布,资源密度区域差异较大,棉花秸秆资源分布水平呈现5种梯度类型,全疆呈现出“南密北疏、西丰东贫”的资源分布特点。
In order to fully understand the economic value and development potential of cotton straw resources in Xinjiang, a comprehensive and systematic estimation was made on the cotton straw resources in Xinjiang by using the corrected grass-grain ratio. Arc GIS software was used to analyze the regional distribution characteristics of cotton straw resources. Using DPS software Factor analysis and cluster analysis method for comprehensive evaluation of cotton straw resources. The results showed that: 1) The amount of cotton stalks in Xinjiang fluctuated with the change of cotton yield. In 2013, the cotton yield in Xinjiang was 2.06 × 10 ~ 6 t, and the amount of cotton stalks collected was about 1.68 × 10 ~ 7 t. Total energy utilization of cotton straw resources, equivalent to about saving about 9.1 × 10 ~ 6t standard coal; 2) The total amount of cotton straw resources in Xinjiang showed a decreasing trend from south to north, cotton resources in southern Xinjiang, northern Xinjiang and eastern Xinjiang were Accounting for 65.75%, 30.97% and 3.28% of the total in Xinjiang. The abundance of resources is flaky and the resource density varies greatly. The distribution of cotton stalks shows five types of gradients. Shu, Xifeng East poor "resource distribution characteristics.
