草地光伏系统生态适宜性的研究进展
Research progress on the ecological suitability of grassland photovoltaic ecosystem
摘要
Abstract
Photovoltaic(PV)solar power generation is experiencing rapid growth,particularly in large-scale cen-tralized systems.This expansion helps reduce reliance on fossil fuels(coal,oil,etc.)and alleviates climate change pressures.Since 2009,global PV installations have increased by approximately 41%and are projected to grow nearly tenfold by 2040.In China,the area dedicated to PV parks expanded from 5.86 km2 in 2010 to 2920 km2 in 2020,reaching about 3712 km2 by the end of 2022.Grassland photovoltaic ecosystems(GPVEs)established in these parks not only optimize solar energy use but also contribute to grassland conservation.Furthermore,they play an increasingly important role in mitigating climate warming and advancing carbon neutrality.This study ex-amines the effects of large-scale PV parks on local microhabitats both within and outside the park boundaries.PV installations alter microhabitat factors,creating variation in conditions across the front,middle,beneath,and be-tween PV arrays.Generally,such disturbances arise from changes in near-surface energy transmission and equilib-rium,leading to modified microclimates,soil temperature,humidity,and physicochemical properties.The adapt-ability and succession of biological communities(including plants,animals,and soil microorganisms)were inves-tigated in relation to these altered habitats,alongside changes in biogeochemical cycles.PV parks can enhance plant productivity,increase aboveground biomass,and improve vegetation coverage.Notable changes in plant density,species composition,and diversity are largely driven by shading effects.Animal communities show vary-ing adaptability as the parks operate,while PV arrays provide shade for livestock,reducing air temperature and skin humidity,thereby lowering heat stress and thermoregulation costs.Soil microorganisms,essential for sustain-ing ecosystem services,are directly affected by terrestrial biogeochemical cycles,especially carbon cycling.PV development influences carbon and nitrogen storage in plants(aboveground and belowground)and soil,as well as greenhouse gas emissions.This work integrates themes of green low-carbon technology,digital intelligence,and sustainable development.It highlights the shortcomings and future development directions of GPVEs in an ecological suitability framework.The findings provide guidance for advancing the green development model of"grassland photovoltaics plus"(e.g.,photovoltaic grass production and grass-light complementary systems)and for promoting integrated desertification control.关键词
