长江经济带矿产资源开发强度时空演化特征及影响因素解析

Spatio-temporal Evolution and the Influencing Factors of Mineral Resources Development Intensity in Yangtze River Economic Belt

矿产资源开发强度是衡量地区矿业经济的重要指标,科学识别矿产资源开发强度的时空演化特征与影响因素,对区域经济可持续发展具有重要意义。综合采矿权、产出规模、开发占地等方面指标测度了2006~2017年长江经济带矿产资源开发强度,并探讨了长江经济带矿产资源开发强度的时空演化特征与其影响因素。研究发现:(1)长江经济带矿产资源开发强度总体呈现上升趋势,且空间分异显著,呈现出西南高、东北低的空间格局;(2)长江经济带矿产资源开发强度总体差距不断扩大,地区内部差异大于地区间差异,其中上游地区内部差异在各地区内差异中占比最大;(3)长江经济带矿产资源开发强度呈现显著的空间正相关特性,且空间相关性不断提升;(4)矿产资源开发强度受到资源禀赋、生态环境及社会经济等因素的影响,其中矿产资源储量、生态环境重要程度、人均GDP和劳动投入是影响长江经济带矿产资源开发强度变化的主要因素。

Mineral resources development intensity is an important index to measure regional mining economy. Scientifically identifying the spatiotemporal evolution characteristics and influence factors of the development intensity of mineral resources is of great significance for the sustainable development of regional economy. This paper combined mining right, output scale, exploitation area to measure the development intensity of mineral resources in the Yangtze River Economic Belt from 2006 to 2017, and discussed the spatiotemporal evolution characteristics and influence factors of the development intensity of its mineral resources. The results show that:(1) Mineral resources development intensity in the Yangtze River Economic Belt is on the rise on the whole, and presents significant spatial distribution with a spatial pattern of being high in the southwest and low in the northwest;(2) The overall gap in the development intensity of mineral resources in the Yangtze River Economic Belt is widening, and intra-regional differences are greater than inter-regional differences, among which the internal differences in the upstream region account for the largest proportion;(3) Mineral resources development intensity in the Yangtze River Economic Belt presents a significantly positive spatial correlation which keeps increasing;(4) Mineral resources development intensity is affected by resource endowment, ecological environment, social economy and other factors, among which the reserves of mineral resources, the importance degree of the ecological environment, GDP per capita and labor input are the main factors affecting the change of mineral resources development intensity in the Yangtze River Economic Belt.
