Abstract

Abstract:

This study investigates the spatiotemporal dynamics of natural grassland NPP and its response to climatic change in Xinjiang Uygur Autonomous Region, China from 2000 to 2018, based on MOD17A3HGF NPP data and related auxiliary datasets (e.g., temperature and precipitation). The different spatial scales (in whole Xinjiang, northern and southern Xinjiang, various prefectures, and different natural grassland types, respectively), inter-annual changes, trend analysis, and partial correlation analysis were adopted to characterize grassland NPP variation. The results illustrate that grassland NPP showed an increased volatility trend from 2000 to 2018, and the mean average of NPP is 0.103 kg C·m^-2. In terms of spatial pattern, it decreases gradually from the western mountains of Junggar, Ili River Valley, Tianshan Mountains, and Altay Mountains to the Junggar and Tarim Basin. Although the grassland NPP of northern Xinjiang (0.149 kg C·m^-2) is higher than that of southern Xinjiang (0.055 kg C·m^-2), its inter-annual fluctuations are greater than that of southern Xinjiang. Grassland NPP in the entire state shows an increasing trend, but the inter-annual changes are distinct. The NPP of 11 natural grassland types (except for alpine deserts) is increasing; however, there are big differences in variable grassland types. Therefore, it is beneficial to the growth of grassland vegetation after 2000 that the warming-wetting trend and mitigation of human interference in Xinjiang. However, anomalies of inter-annual precipitation result in the inter-annual fluctuations of grassland NPP.

Key words: asymmetric warming-wetting, net primary productivity, spatiotemporal dynamics, space earth observation, natural grassland in Xinjiang
