摘 要:为查清云南省沧源佤族自治县竹资源分布现状与分布规律,实现竹资源高效利用,运用ArcGIS工具,采用平均最近邻分析、核密度分析和优化热点分析的方法,研究了沧源县笋用竹资源、材用竹资源和笋材两用竹资源的空间分布规律、聚集程度、分布均衡程度以及区位优势。结果表明:1)沧源县竹资源的总体空间分布格局为聚集型,聚集度中等偏上,其中笋用竹资源和材用竹资源聚集度均大于40%;2)沧源县竹资源总体表现为1个分布核心和多个分布重心的特点,同时竹资源聚类分区明显,有明显的冷、热点地区,空间均衡性较差;3)笋用竹资源、材用竹资源和笋材两用竹资源区位熵最大值分别为1.69、2.20和1.17,前二者出现在班洪乡,后者出现在芒卡镇。研究首次实现了沧源县竹资源空间分布现状的可视化分析,可为当地推进竹产业发展、促进林业经济建设提供参考。In order to clarify the state and the pattern of bamboo resources distribution in Cangyuan Va Autonomous county,Yunnan province,and to realize the efficient utilization of bamboo resources,the spatial distribution pattern,degree of aggregation,degree of balanced distribution,and location advantages are investigated in bamboo resources for shoot production,bamboo resources for timber production and bamboo resources for both shoot and timber production in Cangyuan county,using ArcGIS tools and the methods of average nearest-neighbor analysis,kernel density analysis,and optimized hotspot analysis.The results show that:1)The overall spatial distribution pattern of bamboo resources in Canyuan county is characterized with aggregation,and the aggregation degree is moderately high.The aggregated degree of bamboo resources for shoot production and bamboo resources for timber production is more than 40%;2)The bamboo resources in Canyuan county in general are characterized by one core and multiple centers.At the same time,bamboo resources are in obvious clustering subdivisions,with evident cold spots and hot spots,and the spatial equilibrium is relatively poor;and 3)The maximum entropy values of bamboo resources for shoot production,bamboo resources for timber production and bamboo resources for both shoot and timber production are 1.69,2.20 and 1.17,respectively,with the former two occurring in Banhong township and the latter in Mangka township.For the first time,this study has realized the visualization analysis of the spatial 28distribution of bamboo resources in Cangyuan county,which can provide a reference for promoting the bamboo industry development and facilitate forestry economy growth.
