基于InVEST模型的2000–2020年乌鲁木齐碳储量分布数据集

Abstract

Terrestrial ecosystem is an important part of the global carbon cycle research. As the global carbon cycle can fix CO2 in the atmosphere in soil and vegetation, regional carbon storage is deeply affected by the changes of land use. Urumqi, the capital of Xinjiang Uygur Autonomous Region, is the political, economic and cultural center of the whole region. It is also an important central city and international inland port area in northwest China. With various land cover types, the city is suitable for the study of carbon sequestration in terrestrial ecosystems. The rational layout of its economic and ecological construction has a very important impact on the construction of the Silk Road Economic Belt and the overall layout of China’s westward opening. Based on the data input requirements of the InVEST model carbon storage calculation module, we collected land use data, meteorological data and carbon density data of Urumqi in 2000, 2010 and 2020 to assess the regional carbon storage. The original data source is reliable, and the data processing and calculation strictly follow the professional operating procedures to ensure the accuracy of the data results. In this study, we corrected carbon density data based on meteorological data, which is more compatible with the facts of the study area and can help to improve the accuracy of carbon storage calculation on InVEST model. This study can provide some scientific data reference for the future economic and ecological construction pattern of Urumqi.
