中文摘要：

利用文献统计、因子分析和聚类分析等方法．对山东省农作物秸秆资源量及其区域分布特点进行分析评价。结果表明，2009年全省可收集利用的秸秆资源量为5．86×10^2t，其中玉米秸秆最为丰富，约占总量的47．11％，小麦秸秆、棉花秸秆分别占29．19％和14．6％。秸秆资源总量区域分布呈现自西向东递减的特征，单位播种面积资源分布呈现自北自南、自西向东递减的趋势，人均秸秆资源分布由北向南逐渐递减。利用因子分析、聚类分析方法进行综合评价，可将全省分为4个类型区：资源丰富区、资源较丰富区、资源一般区和资源不足区，整体呈现“西密东疏、西丰东贫”的资源分布特点。

英文摘要：

The methods of literature statistics, factor analysis and cluster analysis were used to ana- lyze the resources of crops straw and its regional distribution in Shandong province. The results showed that the magnitude of crops straw in Shandong province was up to 5.86x107 t in 2009, among which corn stalks had the most percent of 47.11%, wheat straw and cotton straw accounted for 29.19% and 14.6% respectively. It showed that the total amount of crops straw, decreasing from west to east,per unit sowing area decreasing from northern to southern,west to east,and per capita staw resource decreasing from northern to southern gradually. Based on the factor and the cluster analyz- ing, the crops straw resources distribution in Shandong province could be divided into four types, resource-rich region, resource-relative-rich region, resource-normally region and resource-poor region. The whole crops straw resource present the characteristic of west abundant and east poor.
