江西省国家森林乡村的空间分布特征及影响因素

Spatial Distribution Characteristics and Influencing Factors of National Forest Villages in Jiangxi Province

以江西省第一、二批共430个国家森林乡村为研究对象,通过ArcGIS空间分析工具和SPSS相关性分析,对江西省国家森林乡村的空间分布特征及影响因素进行研究,结果表明:空间分布上,江西省国家森林乡村总体呈现凝聚型分布,三大地理区域的集中分布均衡性较低,最集中的为赣北地区,其次为赣中地区;从市域尺度来看,主要集中在赣州、上饶、吉安、宜春、九江5个市。空间密度分布上,江西省国家森林乡村呈现“多核心集聚,连片分布”的特征,受江西省三面环山地形特征的影响,分布密度总体上表现为从东、南、西三面边界向鄱阳湖平原呈阶梯递减的特征。影响因素上,江西省国家森林乡村空间分布受经济、社会、生态和自然地理多重因子的影响,其中主要受地形和水系影响较大,社会经济水平、交通条件等对森林乡村的空间分布也影响较大。

Taking the first and second batch of 430 national forest villages in Jiangxi Province as the research object,the spatial distribution characteristics and influencing factors of national forest villages in Jiangxi Province are studied through ArcGIS spatial analysis tool and SPSS correlation analysis.The results show that:in terms of spatial distribution,the national forest villages in Jiangxi Province generally show a cohesive distribution.The three geographical regions have a low balance of centralized distribution,the most concentrated area is northern Jiangxi,followed by central Jiangxi;from the city scale,it is mainly concentrated in Ganzhou,Shangrao,Ji'an,Yichun and Jiujiang.In terms of spatial density distribution,the national forest villages in Jiangxi Province show the characteristics of“multi-core agglomeration and continuous distribution”.Affected by the topographic characteristics of Jiangxi Province surrounded by mountains on three sides,the distribution density generally shows the characteristics of stepwise decline from the boundary of east,south and west to Poyang Lake Plain.In terms of influencing factors,the spatial distribution of national forest villages in Jiangxi Province is affected by multiple factors of economy,society,ecology and natural geography,mainly affected by terrain and water system,and the spatial distribution of forest villages is also greatly affected by socio-economic level and traffic conditions.
