Examples
- Based on the principle of fuzzy , utilizing the comprehensive evaluation model of limit analysis on the development of water resources , the authors selected evaluation factors include irrigation ratio of total land , coefficient of product water , degree of water exploitation , water supply and demand modulus , per capita water supply and ecological water use ratio to analyze
摘要基于模糊数学理论的区域水资源开发利用阈分析方法，选取灌溉率、产水系数、水资源开发程度、供需水模数、人均供水量和生态用水率7个主要因素作为评价因素，以杭州市区为例进行具体计算与分析。 - First each of the eight factors , i . e . , per capita water resource available , per capita water requirement quantity , environmental water use rate , utilization rate of water resource , industrial water requirement quantity per 10 , 000 industrial product value , water requirement module , regional irrigation rate was analyzed . then the water resource capacity in hejin city was evaluated by applying the fuzzy comprehensive estimation
选取了人均水资源可利用量，人均供水量，生态需水率，水资源利用率，万元工业产值需水量，需水模数，生活需水定额，耕地灌溉率等8个评价因素，利用模糊综合评判模型对其水资源承载能力进行了评价研究，并提出了河津市水资源安全对策。 - According to our analysis , the farmers in quzhou are in the second phase , which means they already have enough food and put much more inputs for earning high yield and high income . ( 4 ) the ground water table was getting down , caused by precipitation decreasing , no river water coming due to the upstream reservoir , complete drainage in rainy season and irrigation using groundwater
( 4 )自然降水量的降低、上游水库的拦蓄，使平原失去了获得水源的机会；内部防洪排沥体系的完善，致使入渗补充地下水减少；耕地灌溉率的增加，导致农业用水量不断加大，这些因素共同作用使区域水资源失去平衡，引起地下水位的下降，从而促使盐渍土表层脱盐。
