A method for restoring vegetation in ecologically fragile areas of coastal heavily saline-alkali land

Abstract

The invention relates to a method for restoring vegetation of an ecologically vulnerable area of a coastal heavily saline and alkaline land. The method includes steps of leveling a land after early spring and configuring plants on the land by more than one or two of four configuration modes including a tree, shrub and herb mode, a tree and herb mode, a shrub and herb mode and a tree and shrub mode. The method has the advantages that preponderant vegetation restoration varieties are imported from abroad, are screened and are combined with Chinese saline-alkali tolerant plants, the plant configuration modes are created, accordingly, purposes that the salinity of soil ranges from 0.6% to 1.5% and the underwater level is lower than 1.5 meters can be achieved, the preponderant vegetation restoration varieties and the plants can be directly planted without replacing farmland soil under the condition that the ground elevation meets construction requirements, and the vegetation restoration modes are low in expense and are promising.

Description

technical field [0001] The invention relates to a vegetation restoration technology, in particular to a method for restoring vegetation in ecologically fragile areas of heavy saline-alkali coastal areas by using biological measures. Background technique [0002] The restoration of fragile ecological areas is the main goal of ecological environment construction in various countries, but the natural status quo of weak soil, declining soil fertility, drought, water shortage, and sparse vegetation in fragile ecological areas makes the realization of this goal face great difficulties. The northern coastal area is an economically developed area focused on development and construction in northern my country. Forestry ecological environment construction is responsible for improving the investment environment in coastal areas, improving the quality of production and living space for residents, protecting agricultural production in agricultural areas, and resisting sea winds, waves, an...

Problems solved by technology

With the increase of the area, the application of this technology has the following disadvantages: (1) The cost is relatively high, 100-200 yuan / ㎡, and the government is under great economic pressure; This kind of ecological environment construction mode is mainly realized through urban landscape environment construction, which can be achieved in economically developed areas. However, the current economic development of various regions in my country is uneven, and it is difficult for economically backward areas to continue to implement this technical system on a large scale.
