Water samples of water environment and hydroecology factorS were collected in April,July,October,January from 2013 to 2015 to explore water environmental carrying capacity condition of Tenggeli Lake in Zhongwei. The factors of ammonia nitrogen ( NH3 -N) ,total nitrogen( TN) ,total phosphorus( TP) ,permanganate index ( CODMn ) ,chemical oxygen demand( CODCr ) ,phytoplankton ShannonWiener index,zooplankton Shannon-Wiener index,zoobenthos Shannon-Wiener index and comprehensive nutrition status index were selected as evaluating indicators,and the method of Artificial Neural Network Model was used to analyze WECC in Tenggeli Lake. The results show that water environmental carrying capacity of Tenggeli Lake were 0. 69,0. 63 and 0. 46 from 2013 to 2015,and the water environmental carrying capacity of Tenggeli Lake was in a state of basic bearing capacity.
