DIFFUL SOLAR PUMP - - Large-scale grid-connected photovoltaic power plants have achieved remarkable results in desertification land management and comprehensive ecological utilization

Issue Time:2020-09-21


Recently, the Qinghai Provincial Department of Science and Technology organized experts from inside and outside the province to evaluate the results of the project of "Desertification Land Treatment and Comprehensive Ecological Utilization of Large-scale Grid-connected Photovoltaic Power Stations". The expert committee believes that the relevant results of the project have been promoted in the Gonghe Golmud Solar Park. The ecological, social and economic benefits are significant and the application prospects are broad.

 

The project studied the causes, characteristics and current status of wind-sand disasters in large-scale photovoltaic power plants, and revealed the mechanism of wind-sand disasters. It also proposes a comprehensive protection system for sand hazards combining solid and resistance according to local conditions. The influence mechanism of large-scale photovoltaic power plants in the experimental areas of Golmud and Gonghe in Qinghai Province on the microclimate of the station area is systematically analyzed. The eco-hydrological effects of large-scale photovoltaic power plants in the alpine and arid areas are discussed. For the first time, artificial biological crusts have been successfully established in the desertification land test area in alpine and arid regions. And systematically study and demonstrate its sand fixation mechanism. Based on the characteristics of alpine and arid desert in the experimental area. Based on near-natural vegetation restoration technology. In the demonstration base for the ecological construction and comprehensive utilization of large-scale photovoltaic power stations, plants such as Lycium ruthenicum, perennial ryegrass, snow chrysanthemum, Artemisia sylvestris, Artemisia ordosica, alfalfa, Astragalus sativa, and salt-tolerant wheat have been tested and introduced. Obvious experimental results have been achieved.
