Ecological restoration method for slope in typical grassland area

Abstract

The invention discloses an ecological restoration method for a slope in a typical grassland area. The ecological restoration method comprises two parts of gentle slope ecological restoration and inclined slope ecological restoration. According to the gentle slope ecological restoration, indigenous plants including aneurolepidium chinense, elymus sibiricus, achnatherum splendens, artemisiafrigida willd, calamagrostis epigeios, elytrigia repens, astragalus adsurgens, melilotoides ruthenica, hordeum brevisublatum, oxytropis myriophylla, bromus ciliatus, koeleria cristata, hierochloeglabra and bromus inermis are planted in a gentle slope area of the typical grassland area for ecological restoration in two modes of single sowing planting and mixed sowing planting. According to the inclined slope ecological restoration, indigenous plants including aneurolepidium chinense, aneurolepidium dasystachys, elymus sibiricus, puccinellia tenuiflora, agropyron cristatum, achnatherum splendens, artemisia halodendron, artemisiafrigida willd, calamagrostis epigeios, elytrigia repens, astragalus adsurgens, melilotoides ruthenica, oxytropis gracillima, oxytropis myriophylla and hordeum brevisublatum are planted in an inclined slope area of the typical grassland area for ecological restoration in two modes of single sowing planting and mixed sowing planting. According to the method, the cold-resistant local plants are adopted to complete ecological restoration, the cost is low, and the survival rate is high.

Description

technical field [0001] The invention belongs to the field of grassland ecological restoration, and more specifically relates to a method for ecological restoration of slopes in typical grassland areas. Background technique [0002] With the development of history to this day, human beings are changing the face of the earth at an unprecedented speed. On the one hand, it has created unprecedented material wealth for human survival. Sex is decreasing, a large number of species tend to go extinct, the foundation of human existence is gradually disintegrating, and protecting the ecological environment has become a focus of attention all over the world. There are indirect and direct reasons for the destruction of the ecological environment, but the root causes are the increase of population, the expansion of human's ecological niche, the increasing occupation of biological products on the earth, and the excessive consumption of natural resources. [0003] In the context of global...

Problems solved by technology

After planting Caragana microphylla, it grows fast and grows well, but it forms a community dominated by only one species, and other plants are difficult to invade, the diversity is poor, and the community is single, and Caragana microphylla is a thorny shrub. Restoration The utilization rate of rear grassland is very low, and herdsmen do not welcome it

These plant varieties are all purchased from other places, and the ecological restoration lacks local native plant varieties
