基于GIS的电能空间分布特征研究

The Research of Electric Energy Spatial Distribution Based on GIS

本文选取我国大陆31个省市的电力能源数据为研究对象,并且按大区域进行划分,以省级和区域级两级角度,对我国电力能源整体空间分布特征、电能结构分布特征、电能密集度以及电能的经济效率等多项指标进行了分析。研究表明:我国电能空间分布的区域差异性明显;除西南地区诸省以及华中地区湖北省外,火电仍然是我国电力能源构成的主体;电能输出密度较高的省区集中在西南地区,而输入密度较高的省区集中在华东和华北地区;电能输入效率较高的省区集中在东部沿海地区,而输出效率较高的省区集中在煤炭和水利资源丰富的内陆地区。电力能源分布的空间差异性使得跨区域协调管理,差异化的电能分配输送十分必要,而这是实现电力资源源在全国范围内的优化配置主要途径之一。

In this article,we select the electric energy data of the 31 provinces and cities in the mainland of China as the research data,and divided into different regions,on provincial and regional level,analyzed the electric energy spatial distribution and structure spatial distribution and concentration and economic efficiency.Research shows that: the spatial distribution of electric energy regional difference apparent;In addition to the South West region and the Hubei province in Central China region,the thermal power is the main portion of electric energy;The high density of electric energy output province are mainly concentrated in South West region,the high density of electric energy input province are mainly concentrated in North China and East China region;The high efficiency of electric energy input provinces are mainly concentrated in the eastern coastal area,the high efficiency of electric energy output provinces mainly concentrated in the coal and water resource rich inland areas.The regional differences of electric energy spatial distribution,so integrate the electric energy resource to enable the inter-regional coordination and variation of electric energy distribution and transportation is very necessary.It is one of the main ways to realize electric energy optimized allocation in the national scope.
