海南省休闲渔业空间分布及影响因素分析

Spatial distribution of recreational fishery in Hainan province and its influence factors

摘要:

科学合理的企业空间布局有利于休闲渔业经营单位减少资源调配成本,发挥区位优势,实现效益最大化。本研究以海南省799个休闲渔业经营单位为研究对象,综合运用最近邻指数、变异系数、核密度分析法、聚类和异常值分析法,借助ArcGIS空间分析工具,从分布形态、分布均衡程度、分布密度等3个维度对海南省休闲渔业经营单位的空间分布特征进行分析,并对其空间分布特征的影响因素进行探讨。结果表明:海南省休闲渔业经营单位整体上呈现集聚型的分布形态,集聚程度由高到低排序依次是琼北区、琼南区、琼西区、琼东区、琼中区;海南省休闲渔业经营单位的空间分布密度具有显著差异性,形成南北两极,零星集聚,沿海环绕内陆的密度特征,密度梯度自沿海向内陆呈现4个等级的递减差度;海南省休闲渔业经营单位的空间分布受交通、市场、景区区位因素的影响显著,符合“沿路”、“环城”、“傍景”的分布规律;同时,人口规模和经济水平也在一定程度上影响休闲渔业经营单位的空间分布。研究结果可为优化海南省休闲渔业企业选址,提高企业经营效率提供科学依据。

Abstract:

Scientific and reasonable enterprise spatial layout is conducive to recreational fishery business units to reduce resource allocation costs and give full play to regional advantages. Taking 799 recreational fishery business units in Hainan province as the research object, the spatial distribution characteristics of recreational fishery business units in Hainan province were analyzed from the three dimensions of distribution form, distribution equilibrium degree and distribution density by nearest neighbor index, coefficient of variation and kernel density analysis, and the influencing factors of spatial distribution were explored using clustering and outlier analysis and vector data buffer method. The results showed that: the distribution pattern of recreational fishery business units in Hainan province is agglomeration type, and the order of agglomeration degree from high to low is Qiongbei district, Qiongnan district, Qiongxi District, Qiongdong district and Qiongzhong district. the spatial distribution density of the recreational fishery business units showed significant differences, forming the density characteristics of north and south poles, sporadic agglomeration and coastal surrounding inland; the density gradient presented four grades of decreasing difference from coastal to inland. the spatial distribution of recreational fishery business units in Hainan province was largely affected by resources of transport, market and tourist, which were mainly located near the scenic spots, around the cities and along the traffic trunk roads. Furthermore, the population size and economic level also partly affected the spatial distribution of recreational fishery business units. The research results can provide a scientific basis for optimizing the location selection and improving the operation efficiency of recreational fishery business units in Hainan province.
