Greening method for southwest Karst region rocky habitat

Abstract

The invention provides a greening method for a southwest Karst region rocky habitat. The method comprises the following steps: planting Alchornea trewioides, plants in a secondary forest, Bermuda grass and Miscanthus floridulus in the southwest Karst region rocky habitat, wherein the plants in the secondary forest are preferably selected from Loropetalum chinense, Sapium rotundifolium and Radermachera sinica. The method is capable of, through introducing three types of grass, shrub and arbor plants, greening the rocky mountain, effectively improving the greening rate, accelerating and promoting the forward succession of the habitat, and bringing the economic benefit to local residents.

Description

technical field [0001] The invention relates to the field of ecological and environmental protection science and technology, and more specifically relates to a greening method for rocky habitats in southwest karst areas. Background technique [0002] The karst area in Southwest China (about 550,000 km 2 ) is the area with the largest karst area, the widest distribution and the most types in the world. The southwest karst area is located in the middle and upper reaches of the Pearl River, and its rocky desertification problem will directly affect the ecological security of the Pearl River Basin, and the key to rocky desertification control is the restoration and reconstruction of vegetation. The intensification of rocky desertification leads to almost complete loss of soil and extreme degradation of vegetation, which eventually leads to the exposure of bedrock and the formation of stony habitats. This kind of habitat basically has no visible soil cover, and its underlying s...

Problems solved by technology

Plants growing in this kind of habitat only use a small part of the rainwater stored in the bottom seal or transverse fissure to survive, and there are very few plants that can adapt to the water environment characteristics of this kind of habitat. greatly reduced abundance

[0003] Although the control of rocky desertification has been strengthened in recent years, it is difficult for the destroyed vegetation to recover quickly, and the vegetation growing on rocky habitats is even worse.

In addition, due to the generally low vegetation coverage in stony habitats, if proper vegetation protection measures are not taken, the exposed limestone and dolomite will be more eroded by rainwater, and the stony habitat will be difficult to grow.
