A Study on the Construction of Eco-corridor Based on Nature Reserves

摘要

The scientific and reasonable construction of eco-corridors between the nature reserves will be helpful in eliminating the habitat isolation and alleviating the negative effect of landscape fragmentation towards bio-diversity and ecological security. Focusing on the nature reserves in Northeast China, in this paper, we extracted the spatial location of the areas and then applied the minimum cost-distance model to develop a connecting resistance index system in terms of land utilization, disturbance intensity and linear surface feature's resistance; the resistance surface was also developed to reflect human's disturbance, and based on the resistance surface as well as the database of the nature reserves, the eco-corridors between adjacent conservation areas were extracted by applying the minimum cost-distance method, and then the corridor network, which was important to protect the bio-diversity in the conservation areas, was obtained by loop computing.
