Abstract

The present invention belongs to the technical field of ecosystems and discloses a method for assessing a recovery potential of a karst ecosystem using soil animals. A measurement method of the recovery potential of the karst ecosystem uses the soil animals as an object; and a field in-situ soil column transplanting experiment and an indoor culture experiment of soil animal egg banks are used to comprehensively evaluate the diffusion recovery potential of the soil animals in karst area and the recovery potential of dormant egg banks. The karst stony desertification typical area of Puding County of Guizhou Province is used as an example; the diffusion recovery potential and influencing factors of the soil animals under different stony desertification degrees in karst of Guizhou are investigated and analyzed to explore the recovery potential of the dormant egg banks of the soil animals under the background of the karst stony desertification and to provide a scientific basis for the restoration and comprehensive prevention of the fragile ecosystems in the karst stony desertification area.

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...
