Abstract

Gross primary productivity (GPP) is a key link in the carbon cycle of terrestrial ecosystems and is very important for maintaining global carbon balance. This paper studied and analyzed the GPP changes of terrestrial ecosystem water conveyance of the Tarim River, Xinjiang, China based on the Google Earth Engine platform; by using MOD17A2H products released by NASA LP DAAC. The results showed that: (1) the ecological environment of the Tarim River has significantly improved after ecological water conveyance. In the early stage of water conveyance, the average GPP of Tarim River growing season was 3675.51 g C·m-2 per season in the middle stage, GPP increased to 4024.09 g C·m-2 per season in the growing season, and raised to 4896.61 g C·m-2 per season in the later stage. From 2000 to 2020, GPP showed an obvious increasing trend in the growing season, with an increased rate of about 90.25 g C·m-2 in each growing season. After 2010, the daily GPP increased more in the upper, middle, and lower reaches, increasing by 2.54 g C·m-2, 2.17 g C·m-2, and 1.74 g C·m-2 per 10 years, respectively. (2) During the growing season (May-October), the diurnal GPP changes of the Tarim River terrestrial ecosystem were significantly different in different regions. Overall, the daily GPP change in the upstream region showed a single peak trend that first increases and then decreases, whereas the downstream region showed a bimodal trend. (3) The ecological water conveyance project of Tarim River is beneficial to the change of GPP in the growing season, especially the change of GPP in June and August.
