Ecological Impact of Photovoltaic Power Station on Regional Forest Land in Yunnan
Through field visits and investigation interviews,the ecological impact of photovoltaic(PV)power stations on regional forest land in Yunnan Province was investigated.The results showed that the construction of PV power station would cause the cutting of arbor and shrub species and the cutting of herb plants within the power station area,but the number and biomass of plant species were not significantly reduced,and some power stations had a slight increase in species due to shading and moisturizing of photovoltaic panels.The construction of power stations had little impact on genetic diversity,but had a certain impact on the ecosys-tem.The implementation of the PV project would change the use of forest land,destroy a certain number of surface vegetation,and destroy the potential aesthetic value of the landscape in the region to a certain extent,but the effect was only partial and small.The soil erosion in the project area was controllable,and the vegeta-tion could be restored through protection measures.There were practical and feasible pollution and impact pre-vention measures in the construction and operation process.The amount of pollutants was small and the dis-charge was up to standard.The project had little impact on the regional atmosphere,surface water,acoustic environment and ecological environment,and would not lead to significant changes in the environmental func-tions of the project site.Based on the survey results,the technical measures and development countermeasures to strengthen the protection of forest land and biodiversity were put forward,and the construction scale of Yun-nan PV power station was warned to realize the PV power generation industry and ecological environment.
