赣州市生境质量及景观格局时空演变分析与预测OA

The intensification of land use change under the background of urbanization is negatively impacted by the ecological environment.Therefore,the assessment of habitat quality is deemed of great significance for the preservation of regional biodiversity and the promotion of ecological security in a sustainable manner.The spatio-temporal evolution of land use patterns was analyzed using land use dynamic attitude.The evolution of habitat quality in Ganzhou city from 2000 to 2030 was predic-ted based on the Markov-PLUS model and InVEST model,and the characteristics of the landscape pattern were analyzed with respect to different habitat quality patches.The results indicated that from 2000 to 2020,the changes in artificial land surfaces and wetland areas were most pronounced,with the maximum and minimum of land use dynamic attitude being reached,respectively.From 2000 to 2030,an average habitat quality index of 0.814 was achieved in Ganzhou city.The main types were low habitat quality and high habitat quality,with the low habitat quality displaying a dra-matic trend,primarily concentrated in the Ganzhou metropolitan area.The dominance of habitat quality patches was reduced,complexity was increased,connectivity was poor,and there was sig-nificant interference by human activity.Therefore,a decisive role is played by land use change in the habitat quality and landscape characteristics of Ganzhou city.The optimal balance of"ecological-economic-social"can be achieved through the rational planning of land use types.
