Description

Technical Field

[0001] The present invention relates to the field of ecological environment governance, and in particular to a photovoltaic ecological corridor and governance system based on transportation lines. Background Art

[0002] Due to its unique geographical and climatic conditions, the Shagohuang region is prone to frequent sandstorms, which have a serious impact on transportation infrastructure such as roads and railways. The invasion of sandstorms not only leads to sand burial and wear of roadbeds and tracks, but also damages signal equipment and other infrastructure along roads and railways, seriously threatening traffic safety and increasing maintenance costs. In the northwest region, frequent sandstorms have become an important factor restricting the long-term stable operation of transportation routes. In order to reduce the damage caused by sandstorms to transportation routes, existing sand prevention measures such as windbreaks, sandbreaks, sand barriers, wind and dust suppression nets, etc., can effectively reduce the direct impact of wind and sand flow on the roadbed, but they also have certain limitations. Traditional sand prevention facilities mostly focus on physical interception, lack long-term support for ecological environment improvement and restoration, and cannot fundamentally solve the problem of desertification.

[0003] In recent years, with the rapid development of photovoltaic power generation technology, photovoltaic panels have been introduced into the fields of sand prevention and control, forming an emerging model of "photovoltaic sand control." This model not only reduces wind speed and sand erosion on the ground through photovoltaic panels, but also provides energy and economic support for ecological restoration. However, when using the "photovoltaic sand control" model to protect the roadbed of transportation routes, regulating the plant growth environment is a major challenge. Water resources are extremely scarce in the desertified areas, requiring scheduling to control soil moisture, which greatly increases operation and maintenance costs. Furthermore, how to comprehensively utilize water resources, avoid water waste, and effectively conserve water and energy are also urgent issues that need to be addressed by existing technologies.
