Problems solved by technology

But now in rocky desertification control projects, there is often no engineering design and measure configuration for different levels of rocky desertification, and the governance method is single, such as only afforestation, resulting in insignificant governance effects

Embodiment 1

[0022] The Guanling-Zhenfeng Huajiang Demonstration Area in Guizhou belongs to the typical intensive rocky desertification area in karst mountainous areas. The total land area of ​​the demonstration area is 5162.11hm2, of which the karst area is 4538.64hm2, accounting for 87.92% of the total land area. The intensity of rocky desertification in the demonstration area is dominated, and the area of ​​rocky desertification is 1351.99hm2, accounting for 29.79% of the total area of ​​karst. The applicant has carried out a pilot project of rocky desertification control in this area, and adopted the following control methods:

[0023] 1) Protect the existing vegetation, remove harmful alien plants through forest land clearing, seedling tending, and protect the growth environment of local species; prohibit grazing on hillsides, set fire to mountains, and establish a strict enclosure management system;

[0024] 2) For the existing ecosystem, through artificial replanting and proper on-de...

Abstract

The invention relates to a treatment method for intensive rocky desertification in a karst mountainous area. The method includes: protecting actual vegetation, cleaning forest land, and establishing a strict enclosure management system; promoting vegetation recovery through artificial complementary planting for complementary afforestation and appropriate bunch planting of cypress, privet, paper mulberry and triadica sebifera; developing economic tree species and Sichuan pepper planting; developing economic fruit tree construction, adopting low and short crop and economic forest interplanting mode to develop forest and grass interplanting, and selecting ryegrass, pennisetum hydridum and honeysuckle as artificial planting grass to solve the problem of shortage of livestock feed; developing rural tourism, constructing a biogas energy system, comprehensively utilizing biogas residue, establishing a forest-bird mode, and modifying original water conservancy facilities, utilizing the roof water collection technology and connecting a roof water collection level ground with a cistern so as to solve the problem about drinking water for human and livestock. By the treatment method, the intensive rocky desertification in the karst mountainous area is treated effectively, water and soil loss is reduced, the trend of rock coverage is restrained, and social and economic coordinated development is realized.

Description

technical field [0001] The invention relates to a control method for intensive rocky desertification in karst mountainous areas. Background technique [0002] The distribution area of ​​exposed and semi-exposed karst areas in China is more than 1.3 million square kilometers, accounting for 13.54% of the total land area. The 550,000 square kilometers of karst in southern China centered on the Guizhou Plateau is the largest and most intensely developed area of ​​tropical and subtropical karst in China and the world. Karst environmental and ecological problems are very typical and representative in the country and the world sex. The special environment and ecology have produced various effects on natural conditions, human survival and economic and social development: on the one hand, the evolution of geological history driven by dissolution, erosion and collapse has formed colorful tropical and subtropical karst landscapes, Occupying a prominent position in the world karst, i...
