Land Use Change Vulnerability Analysis in Typical Forest-Agriculture Ecotone of Northeast China: A Case Study of Mudanjiang City

摘要

Forest-Agriculture ecotone conceptually belongs to ecological crisscross region. It is the overlapping and transition area of farmland and forest in spatial distribution or over passage of time, which often exhibits banded structure. With a case study of Mudanjiang city, Heilongjiang province, this paper analyzed regional evolution of forest-agriculture ecotone and vulnerability characteristics resulting from land use change. Using AHP and GIS technology, this paper conducted a spatial and quantitative assessment of ecological vulnerability in Mudanjiang area according to exposure-sensitivity-adaptability model. The result suggested that overall vulnerability of forest-agriculture ecotone in Mudanjiang was weakly recessive or moderate dominant level.
