Abstract:
China recently announced that it would aim to achieve peak CO2emissions before 2030 and carbon neutrality before 2060(i.e. carbon peak and neutrality targets). Undoubtedly,solar photovoltaics(PV),as a zero-carbon energy source,is going to play a major role in national energy transition. Thus,it is urgent to study an ecological solar photovoltaics pattern(Eco-PV)to reach the dual goals together,renewable electricity generation at the same time sustainable ecosystems. This study first analyzed and summarized the impact of PV arrays on micrometeorology,soil and vegetation,the benefits of carbon sequestration in the PV plant areas,and the evaluation of the value of ecosystem services. A new concept and intentions of Eco-PV was proposed to optimize the integrated value of emissions,ecological and economic benefits under the constraint of economic costs,while also considering the structure,function and service value of the ecosystem. Additionally,an Eco-PV pattern in ecologically fragile areas was proposed based on the characteristic of ecologically fragile areas,and combining the ecosystem process and valuation models of ecosystem services such as InVEST(Integrated Valuation of Ecosystem Services and Trade-offs). As a holic tool,it will put forward on breaking the bottleneck of land use of the PV industry,and identify the optimal developing path to guiding the future Eco-PV industry standard.
