Abstract

Abstract: Photovoltaic （PV） power stations are expanding rapidly as a clean energy source， yet their ecological impacts on desert ecosystems remain insufficiently understood. In this study， we examined the effects of a PV power station， operating for seven years in Hongshagang， Minqin， Gansu Province， on vegetation characteristics and soil physicochemical properties. And， three site types beneath PV panels （BX）， between PV panels （BJ）， and an undisturbed control area （CK） were investigated. The results showed that the Margalef richness index， Shannon-Wiener diversity index， Simpson dominance index， vegetation cover， and aboveground biomass were higher in BX and CK than in BJ. The soil moisture content， organic matter， available potassium， and available phosphorus increased in BX and BJ， whereas pH and electrical conductivity decreased Vegetation coverage and aboveground biomass were significantly negatively correlated with soil electrical conductivity. Overall， after seven years of operation， the PV power station improved soil physicochemical properties and enhanced species diversity and biomass accumulation. These findings provide valuable insights into the ecological effects of PV development in desert regions， offering guidance for sustainable PV station management and ecological restoration.

Key words: Photovoltaic power station, Temperate desert, Soil physicochemical properties, Species diversity, Biomass

摘要： 光伏电站作为清洁能源迅速发展，但其建设对荒漠生态系统的影响尚不明确。本研究以甘肃民勤红沙岗运行7年的光伏电站为对象，调查光伏板下（Under the photovoltaic panels，BX）、板间（Between photovoltaic panels，BJ）及未受干扰区（CK）的植被特征及土壤理化性质，并分析其相互关系。结果表明：BX和CK的物种Margalef丰富度指数、Shannon-Wiener多样性指数、Simpson优势度指数、植被盖度及地上生物量均高于BJ；BX和BJ的土壤含水量、有机质、速效钾、速效磷含量增加，而pH值、电导率降低；植被盖度、地上生物量与土壤电导率显著负相关。总体而言，光伏电站运行7年后改善了土壤理化性质，并促进了物种多样性和生物量增加。本研究为荒漠地区光伏开发的生态影响评估及可持续管理提供了科学依据。
