- Abstract:

The study on spatiotemporal variation of regional land ecological vulnerability contributes to using land resources and protecting the fragile eco-environment to local conditions, and has the important guiding significance for regional sustainable development. This paper took Ning’an City, Heilongjiang Province, as the study area to construct models to evaluate the vulnerability of landscape types and the regional land ecological vulnerability based on remote sensing of 1991, 2000 and 2010. Finally, ordinary Kriging interpolation was conducted to get the distribution map of the land ecological vulnerability in study area. The results showed in 1991, 2000 and 2010, the vulnerability degree of each landscape type followed the the order of farmland > construction land > other land uses > water area > grassland > forestland. Land ecological vulnerability index of the 61.7% of the sample areas increased, proportion of the middle-high vulnerability area increased, proportion of slightly vulnerability area decreased, the land ecological vulnerability exacerbated. The distribution map of the land ecological vulnerability showed that the vulnerability index was the highest in north-central part, extension gradually reducing and middle-high vulnerability area gradually expanded in the study area.
