Abstract: In the present study, land and water sustainable utilization state and trend in Henan Province in 2000-2014 was evaluated by triangle model from 3 aspects of natural resource sustainability, economic society feasibility and ecological environment reasonability. The main influence factors were further identified by grey relational analysis. It was shown that the total level of the utilization was not high, around the fair sustained state and the weak sustained state. The state exhibited 4 obvious trends: T6 trend (weak sustained state) from 2000 to 2002, T3 trend (fair sustained state) from 2002 to 2004, T1 trend (fair sustained state) from 2004 to 2010, T6 trend (weak sustained state) from 2010 to 2014. Factors constraining the promotion of utilization level were mainly from ecological environment system and economic society system. The influence factors included vegetation coverage, effective irrigation rate of cultivated land, population density, pesticides input per hectare and improvement rate of soil and water loss.

Key words: land and water resources, sustainable utilization, triangle model, grey relational analysis, Henan Province
