Embodiment 1

[0026] The researchers carried out the construction of amphibian habitats in an abandoned sand mining field in the hilly section of the main stream of the Wutong River, a first-level tributary of Heilongjiang Province. The specific steps are as follows:

[0027] (1) Recovery plan design

[0028] The restoration area is located on the left bank of the main channel of the Wutong River, with an altitude of 94 m. The land use type of the riverbank zone before sand mining is forest land, which is an excellent habitat for Northeast Rana, Heilongjiang Hyla, and Black-spotted Frog. Perennial sand mining resulted in a large area of ​​exposed shoals with gravel substrates in the dry season, with an area of ​​about 0.45 km 2 , the width ranges from 67 m to 107 m, and the length is about 194 m. The technicians carried out the investigation of the community diversity and habitat conditions of amphibians during the vigorous breeding period. The results showed that no Cauura were found in t...

Abstract

The invention discloses a cold region abandoned sand yard amphibian degraded habitat restoring method. The method comprises the following steps of 1 restoring scheme design, 2 geomorphic type modification, 3 rapid vegetation restoring and 4 ecological habitat building. The habitat quality of amphibians can be rapidly and effectively improved, then, the biological diversity of the water ecosystem is improved, the ecosystem functions are restored, and the method is low in cost, good in ecological benefits, and suitable for being used and popularized in regions seriously and physically disturbedby cold region rivers.

Description

technical field [0001] The invention relates to a method for restoring the degraded habitat of amphibians in abandoned sand fields in cold regions. Background technique [0002] As a key link in the energy flow and material cycle of the ecosystem, amphibians are a necessary condition for the conservation of biodiversity in river ecosystems. The range of activities of amphibians is limited to a specific humid environment, and they are sensitive to the habitat quality of rivers, so they are good indicator organisms for environmental monitoring. However, due to the negative impact of high-intensity human disturbance, amphibian habitats have been seriously degraded, and the populations have declined rapidly. Taking Heilongjiang Province as an example, the Northeast Rana is a key local protected wild animal in Heilongjiang Province. The Northeast Rana has been included in the China Red Book of Endangered Animals, and it is a vulnerable wild animal that should be paid attention t...
