连云港市“十二五”农业灌溉用水有效利用系数测算与评价

摘要

By using the head-end measurement method,the agricultural irrigation water use efficiency in Lianyungang during the 12th Five-Year was measured out based on the experimental data of the 21 typical sample irrigations. The result is analyzed and evaluated. Three most important factors influencing the agricultural irrigation water use efficiency are found out. Suggestions for improving the agricultural irrigation water use efficiency were put forward.%利用首尾测算法，以21个典型样点灌区实测资料为基础，测算出连云港市“十二五”农业灌溉用水有效利用系数，并进行了分析与评价，筛选出影响灌溉水有效利用系数的3个最主要因素，提出了提高灌溉水有效利用系数的建议。
