摘要/Abstract

摘要： 多年来山西省主要以煤炭资源带动发展,但生态环境受到破坏,植被净初级生产力(NPP)是衡量区域生态环境的重要指标,研究矿区植被NPP对于区域生态修复及可持续发展、高质量发展具有重要意义。本文以山西省轩岗矿区为例,运用Landsat、MOD17A3H、DEM、气象、人口等数据,综合CASA模型、一元线性回归、Hurst指数及地理探测器方法,揭示了矿区植被NPP时空变化特征,并分析了其驱动因素。结果表明:①在时间尺度上,2000—2021年轩岗矿区植被NPP高值区呈显著上升趋势,多年平均值为370.79 gC/(m²·a);②在空间尺度上,矿区植被NPP具有显著异质性,总体呈现从西南到东北逐渐降低的特征,由大到小依次为中值区(53.63%)、高值区(41.99%)、低值区(4.38%);③在变化趋势上,矿区植被NPP以增加趋势为主,且未来将以持续加剧为主,植被生长环境仍有较大挑战;④从驱动因素上分析,矿区植被NPP受因子影响由大到小依次为:土地利用(0.109)、海拔(0.088)、人口密度(0.075)、坡度(0.042)、降水(0.020)、气温(0.014)、坡向(0.042)。

Abstract: Over the years, the development of Shanxi province has been mainly driven by coal resources, but the ecological environment has been destroyed. The net primary productivity of vegetation (NPP) is an important index to measure the regional ecological environment. The study of NPP of mining area vegetation is of great significance for regional ecological restoration, sustainable development and high-quality development. Taking Xuangang mining area in Shanxi province as an example, this study used Landsat, MOD17A3H, DEM, meteorological and population data, and integrated CASA model, monadic linear regression, Hurst index and geographical detector methods to reveal the spatio-temporal variation characteristics of NPP in the mining area, and analyzed its driving factors. The results show that: ①In terms of time scale, the NPP high value area of vegetation in Xuangang mining area shows a significant upward trend from 2000 to 2021, and the average annual value is 370.79 gC/(m²·a); ②In spatial scale, NPP of vegetation in the mining area has significant heterogeneity, showing a gradual decrease from southwest to northeast, with the median area (53.63%)、high value area (41.99%)、low value area (4.38%),from the largest to the smallest; ③In terms of changing trend, NPP of vegetation in mining area is mainly increasing, and will continue to intensify in the future, and the vegetation growth environment still faces great challenges; ④From the perspective of driving factors, the NPP of vegetation in mining area is affected by land use (0.109)、elevation (0.088)、population density (0.075)、slope (0.042)、precipitation (0.020)、air temperature (0.014)、slope direction (0.042),from the largest to the smallest.
