Problems solved by technology

However, there are the following disadvantages: level-level land preparation eliminates individual differences in plantation forests, which leads to the uniformity of individual competitiveness of plantation forests, which cannot promote self-thinning, resulting in low-efficiency forests, and also makes it impossible to carry out self-renewal succession of plant...

Embodiment 1

[0024] Embodiment 1 A kind of method for afforestation and land preparation of water source conservation forest

[0025] A method for afforestation and land preparation of water conservation forests, comprising the steps of:

[0026] A Preliminary survey of selected water conservation forest areas in North China, including investigation of topographical conditions of water conservation forest areas, determination of regional size and afforestation area, afforestation density and configuration of water conservation forests, and investigation of the number of shrubs, weeds, and roots in the afforestation areas growth status, etc.;

[0027] B. Carry out forest land clearing in the water conservation forest area:

[0028] ①For dead cut roots, they should be partially excavated according to the afforestation density and row spacing configuration;

[0029] ② For the cut roots that have germinated and regenerated, they should be reconstructed in a planned way according to the affor...

experiment example 2

[0038] The construction of water source conservation forest vegetation in Banchengzi River Basin, Miyun, Beijing aims to enhance the ecological hydrological function of water conservation vegetation, improve soil infiltration performance, improve soil conditions, store water and soil, and purify water quality. Specific steps are as follows:

[0039] A Preliminary survey was carried out on the selected area. The natural environment characteristics of Miyun Banchengzi watershed are shown in Table 1.

Abstract

The invention relates to an afforestation and soil preparation method for water conservation forest in north China, the method comprising following steps: (1) preliminary investigation of a selected water conservation forest area in north China; (2) forest land clearance in the water conservation forest area; (3) in the water conservation forest area, soil preparation with narrow horizontal strips and fish-scale pits along the contour line in an alternate form. According to the afforestation and soil preparation method, by performing investigation on the selection indexes of forest areas and performing soil preparation with narrow horizontal strips and fish-scale pits along the contour line in an alternate form, the soil porosity and infiltration capacity are increased so that soil and water conservation is achieved. The method can be applied under all kinds of terrain conditions. The method has following beneficial effects: small ground-breaking surface and small investment. By use of the method and in the long run, the differences in soil water distribution can be changed; the mechanism of selection through competition between individual vegetation can be promoted; stability and long effectiveness can be maintained; water and soil conservation and water purification can be achieved.

Description

technical field [0001] The invention relates to an afforestation and site preparation method for water source conservation forests, in particular to an artificial forest afforestation and site preparation method aiming at making full use of water source conservation forests to store water, conserve soil and purify water quality. Background technique [0002] Artificial afforestation is one of the important ways to expand forest resources and improve the ecological environment. The quality of artificial forests in the Tushishan area of ​​North China is generally not high, the forest protection efficiency is low, the water conservation capacity is poor, soil erosion is serious, the ecosystem structure is disordered, dysfunctional, and the ecological environment is very fragile. [0003] Water conservation forest is an artificial forest species with special significance. It not only has the ecological benefits, economic benefits and social benefits that forests generally have, ...
