Abstract: Starting with analysis of irrigation demand index in the 10 districts all over China, this study focuses on economic value of water (EVW) for irrigation based on the cost-benefit information of four main crops during year 2000 to 2005. The non-water cost deduction method (NCDM) is applied in EVW calculation for these crops by districts. The result shows the applicability of crop plantation and its regional characteristics. Therefore, further suggestions of advantageous districts, planting strategy and policy priority to the breed of grain and cotton are proposed. This study also provides water-related information for decision making at national level in grain and cotton development and food security.

Key words: irrigation demand index, economic value of water, non-water cost deduction method, advantageous district, planting strategy
