新疆棉花秸秆资源量估算及其区域分布研究

Estimation and utilization of the cotton straw resource in Xinjiang

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 developing potentials of cotton straw resources in Xinjiang,we selected the revised grass guppies to estimate comprehensively the cotton stalk resources in Xinjiang, applied ArcGIS software to analyze the characteristics of the regional distribution of cotton straw resources, and combined DPS software with factor analysis and cluster analysis method to evaluate the cotton stalk resource. Results show that： （1） The stalk resource in Xinjiang showed fluctuant growth with the cotton yield changes. The cotton yield in 2013 was 2.06 ×10^6t, the collectable cotton stalk resources was about 1.68 ×10^7t. If all the cotton stalk resource in 2013 were utilized as the energy, it was equivalent for saving about 9. 1 × 10^6t standard coal. （2） The total amount of the cotton stalk resource in Xinjiang presented a decreasing trend from south to north regions; 65.75% of the cotton straw in Xinjiang were produced in south region, 30.97% were in the north region and 3.28% in the east region. The resource abundance showed a patchy distribution, regional differences of the resource density were large, the cotton stalk resources distribution level showed 5 types of gradient, Xinjiang showed the characteristics of the resources distribution as follows ＂dense in the south , sparse in the north, fertile in the west and poor in the east＂.
