Problems solved by technology

The construction of photovoltaic projects in Northwest China will inevitably disturb the surface and destroy the vegetation on the surface. The underlying loose materials will be activated immediately, providing a rich source of materials for the occurrence of wind erosion. When the air flow flows through the project area, especially the place where the photovoltaic panel foundation is, the wind erosion intensifies, and the erosion occurs, causing the foundation to be hollowed out; while in a relatively open place without equipment and other barriers, the wind speed decreases sharply, and sand accumulates, causing burial, which seriously affects Normal construction and operation of production and construction projects

Embodiment 1

[0042] A method for establishing an ecological restoration system applicable to photovoltaic power stations, comprising the following steps:

[0043] Step 1: Current situation investigation: investigate the current situation of the photovoltaic power station to be treated, and determine the ecological restoration zone according to the current situation of the photovoltaic power station to be treated;

[0044] Step 2: According to the survey status in Step 1, analyze the existing vegetation types, distribution and succession rules in different regions, and screen the native pioneer plant species and biological crust species;

[0045] Step 3: According to the zoning and pioneer plants in Step 1 and Step 2, it is determined that there are three implementation methods for restoration, which are engineering measures, plant restoration measures and biological crust measures;

[0046] Step 4: According to Step 2 and Step 3, determine

[0047] The engineering measures are: one or bot...

Embodiment 2

[0058]Compared with Embodiment 1, the difference of this embodiment is that the partitions in step 1 include: the peripheral area of ​​the photovoltaic panel, the area between the photovoltaic panels and the area under the photovoltaic panel.

[0059] said

[0060] Periphery of photovoltaic panels: adopt engineering measures and plant restoration measures;

[0061] Photovoltaic panel room: adopt engineering measures and plant restoration measures;

[0062] The area under the photovoltaic panels: adopt engineering measures, plant restoration measures and biological crust measures.

[0063] According to the analysis of the existing vegetation types, distribution and succession rules in different zones of the photovoltaic power station construction project in step 2, it is determined that the final screening native pioneer plant species are Sedum notoginseng and Pennisetum, and the type of biological crust is moss. Skin.

Abstract

The invention relates to the field of ecologic environment restoration, in particular to a method for building an ecologic restoration system applicable to a photovoltaic power station and application thereof. According to different wind erosion characteristics of a research region, a grass box sand-protecting barrier, gravel gland measures and red mud coverage measures are adopted, the phenomenon that sand wind continues to erode the earth's surface can be effectively prevented, local pioneer plants are planted inside the grass box sand-protecting barrier, on the basis of biologic inoculation crusting measures, a land cover is rapidly formed, ecologic restoration is performed, in the later period, a control and monitoring mechanism is built, vegetation is recovered at the damaged earth's surface, plant communities are in normal succession, and a stable colonic system is formed.

Description

[0001] Technical field [0002] The present invention relates to the field of ecological environment restoration, in particular to a method suitable for establishing an ecological restoration system in a photovoltaic power station and its application. Background technique [0003] Northwest windy and sandy and Gobi areas are sparsely populated, but rich in light resources, and have unique advantages in developing photovoltaic power plants. In recent years, photovoltaic power stations in Qinghai, Xinjiang, Gansu, Shaanxi, Tibet and other windy and sandy and Gobi areas have developed rapidly. Churn issues cannot be ignored [1] . The construction of photovoltaic projects in Northwest China will inevitably disturb the surface and destroy the vegetation on the surface. The underlying loose materials will be activated immediately, providing a rich source of materials for the occurrence of wind erosion. When the air flow flows through the project area, especially the place where t...
