| 利用ArcGis9.3GeoDA10.0 软件对贵州省各县的化肥施用量进行空间自相关分析。分析了贵州省各县
2000，2010 年化肥施用量的空间关联性2010 年各县的化肥施用量和粮食产量的空间关联性。结果表明院2010 年化
肥施用量总体呈现西高东低的趋势，贵州省各县2000，2010 年化肥施用量在空间关连上存在正相关性，化肥施用量
的分布并不是随意分布的，而是在空间分布上具有集聚Moran 散点图显示位于一、三象限区的县比较多，二、四象
限相对较少，化肥施用量在空间分布上不均衡。化肥施用量在空间上对粮食产量也存在正的相关性，说明化肥施用
量较高的地区粮食产量也较高。总体而言，贵州省的化肥施用量呈现野高高冶、野低低冶集聚分布。 |

| This paper used ArcGis9.3 and GeoDA10.0 software to establish spatial autocorrelation analysis of counties
in Guizhou, analyzed the spatial association of fertilizer consumption of each county in 2000 and 2010, it also analyzed the
spatial association between fertilizer consumption and grain yield of each county in 2010. The results showed that the
tendency of fertilizer consumption presented high in western areas and low in eastern areas in 2010. The spatial correlation
of fertilizer using amount in each county was positive in 2000 and 2010, the fertilizer consumption distribution is not
entirely random, but is clustered on the space. Moran scatter plot showed that more counties were located in the first and
the third quadrants, while relatively less in the second and the forth quadrants, which demonstrated their distribution was
not balanced.For the grain yield, the spatial correlation of the fertilizer consumption was also positive, which demonstrated
the higher the fertilizer application, the higher grain production. Generally speaking, Guizhou fertilizer consumption
presented high-high and low-low clustering distribution |
