Description
Technical field
The present invention relates to the prevention and controls of the potential stony desertification in a kind of Karst Mountain Areas.
Background technology
China is exposed, half exposed karst distribution area reaches more than 1,300,000 square kilometres, accounts for 13.54% of territory total area.Karst Area In South China centered by Guizhou Plateau 550,000 square kilometres, be China and even the world is tropical, subtropical zone karst distribution area is maximum, grow the strongest area, environment of karst all has very strong typicalness and representativeness with ecological problem in national and the world.Special environment and ecology all creates many-sided effect to natural conditions, human survival and socio-economic development: on the one hand; the earth history differentiation acting as power with corrosion, erosion and avalanche defines the colourful torrid zone, subtropical zone karst landscape; the status highlighted is occupied in world's karst; high-grade world natural heritage, in the urgent need to protection.On the other hand, with population overloading, deforest and reclamation, the human history that soil erosion and stony desert turn to core develops the degeneration exacerbating fragile ecological environment, and socio-economic development is delayed, has very strong representativeness in world's karst, in the urgent need to administering.
Karst is a huge Man Land relationship system, and the ecosystem fragile in system under moving obstacle, defines and has the exclusive environmental degradation phenomenon in karst, be i.e. stony desertification in strong people.Stony desertification is under Vulnerable kast ecologicalenvironmenin, the irrational socio-economic activity of the mankind, cause particularly thorny, the vegetation deterioration in people ground, soil erosion, rock gradually exposed, fertility decline lose, earth's surface visually presents the evolution process being similar to desertification view.The generation of stony desertification, being a multifactor result formed that interacts, be not simple natural process, but a nature and society economy is tightly correlated with, and takes factor as the leading factor and the environment that causes worsens, the process of land deterioration and stony desertification with human activity.
Stony desertification intensity in Karst Mountain Areas can be divided into six grades according to the exposed rate of rock and vegetation and the capped rate of soil, be respectively without stony desertification, potential stony desertification, slight stony desertification, moderate stony desertification, intensity stony desertification and extremely strong stony desertification, potential stony desertification refers to the exposed rate of rock between 20-30%, vegetation or the capped Karst Mountain Areas of rate between 80-70% of soil.This region woods grass-shrub vegetation is sparse, becomes native condition good but soil erosion is obvious; There is the trend that rock is exposed.Also do not have specially for the comprehensive processing method of the potential stony desertification in Karst Mountain Areas in prior art, the habitat conditions of different brackets stony desertification, the origin cause of formation is different, and the configuration of its recovery process, mechanism, administration way, engineering also needs variant.But now in Rocky Desertification Control engineering, often do not carry out engineering design and Measures program for different brackets stony desertification, and administration way is single, such as, is only afforestation, causes regulation effect not obvious.Namely the present invention is the stony desertification treatment method for this kind of region.
Summary of the invention
The invention provides the prevention and controls in potential stony desertification region, a kind of Karst Mountain Areas, the method is specially for the method for integrated control in potential stony desertification region, Karst Mountain Areas, by the control of the method, the soil erosion of Karst Mountain Areas obviously reduces, rock is exposed is contained, human society and the economy in this region are developed in harmony.
For achieving the above object, the present invention adopts following technical scheme:
A prevention and controls for the potential stony desertification in Karst Mountain Areas, comprises the steps:
1) soil ladderization and reclamation: build stone ridge transforming slope into terrace, supporting field produces sidewalk, and containment soil erosion further develops; Utilize walnut, capsicum, peanut, rye grass to build biological transforming slope into terrace, both reduced soil erosion, and increased economic well-being of workers and staff again; Improve soil cultivating mode, promote minimal till, no-tillage, shift of crops, applies fertilizers scientifically, and changes soil physico-chemical property, reaches reclamation object;
2) variety of crops improvement: change the general layout of sloping upland based on maize planting, development fruit forest zones industry and animal husbandry;
3) sloping upland Compound Management: specification combination of forest and grain plant pattern, guides villager to develop woods grass, woods medicine, Crop-grass intercropping, sets up woods grass tree-dimentional growing model, makes full use of land resources;
4) water resources development and utilization and Optimized Operation: set up set roof rain system, be made up of roof amatsubo, aqueduct, filtering ponds and water cellar, namely concrete is utilized to build roofing amatsubo, and water cellar is built under room, with pipeline, water in water cellar is conveyed within doors again, builds simple running water and drink for people and animals;
5) agricultural water-saving irrigation: utilize machinery well-digging, extract underground water, builds head-tank at control area height point, with field, domatic pond pipeline, forms irrigation network, adopt sprinkler irrigation technique;
6) participatory eco-species grows: select walnut, the winter peach, rye grass and Trifolium repense, the standardized planting of development fruit forest zones+herbage;
7) biogas comprehensive development and utilization: construction methane generating pit, utilizes biogas to cook, and natural pond slag applies fertilizer, and sets up " pig-natural pond-fruit forest zones " yard gas pipe.
Outstanding feature of the present invention is:
1, also do not have in prior art specially for the comprehensive processing method of the potential stony desertification in Karst Mountain Areas, the habitat conditions of different brackets stony desertification, the origin cause of formation is different, and the configuration of its recovery process, mechanism, administration way, engineering also needs variant.But now in Rocky Desertification Control engineering, often do not carry out engineering design and Measures program for different brackets stony desertification, and administration way is single, such as, is only afforestation, causes regulation effect not obvious.The present invention is separately for potential stony desertification region, and adopt comprehensive, specific technological means to administer, regulation effect is obvious.
2, administering method of the present invention is a comprehensive governance process, and all independent measures must be joined together, and just can play the effect of the comprehensive regulation.
3, from environment, humanity, economical, social development is comprehensively taken measures, and is not only to get on change from environment.
Detailed description of the invention
