Spatial-Temporal Evolution and Prediction of Habitat Quality in Lindian County
Taking Lindian County of Heilongjiang Province as the study area,using the land use survey data in 2000,2010 and 2018,the spatiotemporal evolution and prediction of habitat were carried out by using PLUS,In-VEST and other methods.The results showed that:①The land use in Lindian County was mainly cultivated land,followed by grassland and construction land.The ratio of forest land to water surface was very low.②From 2000 to 2018,the area of cultivated land and unused land expanded by 111.26 km2 and 39.14 km2,respectively,and the area of forest land and grassland decreased by 26.61 km2 and 130.69 km2,respectively.③Taking 2018 as the base period,the land use simulation of Lindian County in Heilongjiang Province in 2030 was obtained,and the results showed that the Kappa coefficient was 0.85,which proved that the simulation accuracy was high and the habitat quality simulation research could be carried out.The results of the 2030 scenario simulation show that there are significant differences in the land use simulation maps under different scenarios;the expansion of agricultural land and water surface construction land in the scenario,the area of forest land and aquatic plant land including unused land are also decreasing.The habitat quality is decreasing,and the habitat is facing the danger of degradation,which provides a certain theoretical and practical basis for the ecological environment construction and green eco-logical construction in Lindian County,Heilongjiang Province.
