Embodiment 1

[0015] In a typical karst mountainous area in Guizhou, rocky desertification is serious, and the following comprehensive measures are taken to control rocky desertification: 1) On the basis of comprehensive planning, different types of mountain closures and afforestation measures are adopted to implement practical, effective and feasible closures Measures to prohibit mowing, grazing, logging, firewood and other forms of human and animal activities that are not conducive to plant growth and development, reduce the adverse effects and interference of human activities, and promote the natural restoration of vegetation; increase management in key areas In terms of intensity and investment, adopt the principle of adapting measures to local conditions, suitable trees and grasses in the right place, plant in a niche environment, and carry out necessary artificial planting and artificial promotion measures;

[0016] Plant a variety of economic forests and grasses suitable for karst are...

Abstract

The invention relates to a comprehensive prevention and control method for karst mountain area stony desertification. The comprehensive prevention and control method includes the steps that hillsides are closed to facilitate afforestation, planting is performed in an ecological niche according to the rules of adjusting measures to local conditions and matching tree and grass species with the site, necessary artificial planting and artificial updating promoting measures are taken, and various commercial forest and grass suitable for karst areas are planted; grain-commercial crop-forage grass crop rotation interplanting is adopted, and leguminous green manure and forage grass with vicia villosa, Chinese milk vetches and medicago sativa as main parts are developed and popularized; high-quality beef and mutton sheep varieties suitable for forage grass resources of the karst areas are selected and bred; a country ecological economy mode with agriculture, forest, animal husbandry and sideline coordinate development is formed; water resources are utilized according to the local conditions. Through the prevention and control method, stony desertification of the karst mountain area is effectively treated, water and soil loss is weakened, the rock exposing trend is restrained, and society and economy are developed coordinately.

Description

technical field [0001] The invention relates to a method for comprehensive prevention and control of 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...
