Effects of Land Use Change on Ecosystem Carbon Storage in Hami
Based on InVEST model,the changes of carbon storage and its response to land use change in Hami from 1990 to 2020 were evaluated.The spatial driving factors of carbon storage were analyzed by optimal parameter geographic detector model,and the ecosystem carbon storage in 2040 was predicted by PLUS model.The results showed that from 1990 to 2020,the area of cultivated land,grassland and construction land increased,while the area of unused land,forest and water area decreased.The ecosystem carbon storage in-creased by 3 855.93×104 t,showing a spatial distribution characteristic of high in the middle and low in the sur-rounding areas.Land use and human disturbance were the main driving factors.The conversion of unused land to grassland was the main reason for the increase of carbon storage,and the conversion of ecological land to con-struction and unused land was the leading factor for the decrease of carbon storage.The predicted value of eco-system carbon storage in Hami in 2040 was 50 525.62 ×104 t.Yizhou District and Balikun County were the main areas of carbon storage increase in the future.
