Regional Water Resources Optimization Under Resilience Constraint

Hongxinglong administration is located in the Sanjiang Plain, Heilongjiang Province, and accounting for one-reclamation land area larger. In recent years, with the increasing economic, population, industry, rapid urbanization, and agricultural water resources development and utilization of resources and the environment at the expense of the cost, the model is not reasonable, low resource utilization efficiency, resulting in a general decline in the water table, soil erosion, deterioration of water quality, wetlands shrink, these factors have become the key to restricting the sustainable development of agriculture, in this context, to strengthen the resilience of agricultural water resources system construction, ease pressure on agricultural water resources, to achieve the Sanjiang Plain Agricultural Sustainable development of the inevitable choice. From the standpoint of protecting the interest of sustainable development of agriculture, the use of variable fuzzy matter-element model and improved model separately for each farm Hongxinglong administration to evaluate the resilience of agricultural water resources, determine Hongxinglong administration, the agricultural water resources resilience of each farm situation and on this basis to achieve optimal allocation of water, the final effect analysis, to guide the rational use of water resources, coordination of social, economic and environmental development provides a strong reference.(1) According to Bureau of Heilongjiang Province Hongxinglong annual data provided by the Authority Water Authority, the Authority precipitation data from each farm over the years, all farms and groundwater depth information on meteorological data, thus qualitative selection Hongxinglong Agricultural Water Resources Authority, the resilience of evaluation and the use of principal component analysis- quantitative correlation screening evaluation indicators: the proportion of surface area selected, the annual per capita water consumption, the amount of pesticide use per unit area of arable land, agricultural water quota, the proportion of agricultural water use, soil erosion rates, forest coverage, 11 indicators waterlogged area ratio, the per capita net income, population density, GDP growth and other components of the evaluation system of agricultural water resources bureau Hongxinglong resilience. And the article used CRITIC method to determine the evaluation index weights.(2) Each model and improve the use of variable fuzzy matter-element model of water resources evaluation system resilience of agriculture Hongxinglong administration evaluated and compared the results of its evaluation to determine the final grade resilience of the final results showed that: Shuangyashan, 853,Beixing and 852 farm resilience of agricultural water resources for grade for grade Ⅱ, Raohe, 291,597,Hongqiling, Youyi, Jiangchuan, Baoshan and Shuguang farm resilience of agricultural water resources for grade Ⅲ, and use GIS software to draw Hongxinglong administration agricultural Water Resources resilience rating partition and draw partition map.(3) In order to 12 farms of Hongxinglong administration of evaluate the results of the agricultural water resources resilience,water supply capacity, water systems need water capacity, variable non-negative constraints. In order to achieve harmonization of economic and social benefits, as the ultimate goal of sustainable development, the establishment of Hongxinglong Authority in 2015 and 2020 planning horizon optimal allocation of water resources in the model, the use of immune particle swarm optimization algorithm to solve the model, and monthly basis groundwater and precipitation for information. The results show that: the limited amount of water Hongxinglong administration, and can not fully meet the agricultural water use, and the large amount of the overall shortage, water supply and demand contradiction; moreover, Hongxinglong administration planning year to improve water conditions, groundwater resources effective protection, thereby determining the immune particle swarm optimization is an effective way to Hongxinglong water resources optimization configuration.
