The invention belongs to the technical field of ecosystems, and discloses a method for evaluating the restoration potential of karst ecosystems by using soil animals. Indoor culture experiment of soil animal egg bank to comprehensively evaluate the dispersal recovery potential and dormant egg bank recovery potential of soil animals in karst areas. The present invention takes Puding County, Guizhou Province, a typical area of karst rocky desertification as an example, to investigate and analyze the diffusion recovery potential of soil animals and its influencing factors under different degrees of rocky desertification in Guizhou, and to find out the dormant eggs of soil animals under the background of karst rocky desertification. library recovery potential. In order to provide a scientific basis for the restoration and comprehensive prevention and control of fragile ecosystems in karst rocky desertification areas.
Description
technical field [0001] The invention belongs to the technical field of ecosystems, and in particular relates to a method for evaluating the recovery potential of karst ecosystems by using soil animals. Background technique [0002] The karst ecosystem is a fragile ecosystem that has been degraded on a large scale due to irrational development and utilization by humans, seriously threatening the agricultural production environment and even human survival. Assessing the restoration potential of degraded karst ecosystems is of great significance for the restoration and reconstruction of karst ecosystems. The existing evaluation methods are mainly based on the restoration of aboveground vegetation, but because the plant growth cycle is long, and related work can only be carried out in situ in the wild, it takes a long time and requires a lot of manpower and financial resources. Soil animals are an important part of biodiversity. They have a large number of species, high density...
