Abstract:: Land use change is an important driver of carbon storage in terrestrial ecosystem. Therefore, we introduce the ecosystem services-based land use change vulnerability assessment method to study the effects of land use change on carbon storage and evaluation based on land use change and carbon storage in Heilonggang basin in Julu County, to analyze land use and intensity changes of Julu County in the period from 2000 to 2015, and to study the regional carbon storage changes in vegetation and soil. The results showed that:(1) from 2000-2005, the study area of cultivated land, construction land and unused land area decreased continuously in the area but the unused land area increased, causing the acceleration of carbon loss, and resulting in vulnerability of ecosystem carbon storage in response to land use intensity changes, every increase of land use intensity index a unit of vegetation, soil, total carbon reserves reduced by 366.6 thousand tons of C, 10.3 thousand tons of C and 376.7 thousand tons of C; (2) from 2005 to 2010 and from 2010 to 2015, with the government’s rational land use regulation, each increase of land use intensity index of a unit, the total ecosystem carbon reserve increased by 12.4 thousand tons of C and 10.6 thousand tons of C, continued to show the potential positive effect, carbon sequestration is also increasing, so the reasonable adjustment of land use structure, strengthening planning and management will be reduced key vulnerability of ecosystem carbon storage to land use change.
