Abstract

Abstract: Based on the Global News-2 model, the inflow nitrogen load of Jialing River basin in 1988, 1999, 2007 and 2018 was calculated, and the nitrogen flux of hydrological stations in Jialing River basin was verified to analyze the temporal and spatial distribution characteristics and sources of the inflow nitrogen were analyzed. The results showed that Global News-2 model simulated the inflow nitrogen load of Jialing River basin well, and during 1988—2018, the inflow nitrogen load of Jialing River basin increased by 380 000 t, from 6.3×10⁵t to 10.1×10⁵t; the temporal and spatial variation of the inflow nitrogen load of Jialing River basin was obvious, which was greatly affected by runoff. The Fujiang and Qujiang River systems were the main sources of nitrogen in Jialing River basin. The nitrogen contribution of the two basins accounted for about 70%; there was a large difference of nitrogen load in different counties and cities and different land use types, and the nitrogen load values of cultivated land and residential areas were high; the chemical fertilizer application was the primary source, contributing 31.6%~49.0% of nitrogen in the basin.

Key words: inflow nitrogen load, Global News-2 model, source analysis, Jialing River basin, temporal and spatial evolution
