5、.350.450.55根据安徽省广德县石门卡水库除险加固工程初步设计报告（报批稿）石门卡水库的汇水面积为6.85 km2。（4）水库附近用水量情况。用水量分析石门卡水库位于新杭镇牛头山村，属在册重点小（一）型水库。水库的集水面积6.58km2。水库以灌溉、防洪为主，兼有工业用水和水产养殖功能。（1)农业用水量水库设计灌溉面积为2000亩，本次按照2000亩计算。根据相关规范，灌溉保证率为75%。根据计算，多年平均补充灌溉用水量55万m3，p=75%保证率补充灌溉水量为66万m3。由于灌溉技术水平的提高和灌溉工程的不断完善，规划水平年灌溉用水定额将有所降低，节约的灌溉用水量可用于增加灌溉面积，因

6、此，规划水平年的农业灌溉用水量将与现状水平基本相当。参照广德县卢村水库及浙江省部分小型灌区的资料，渠系水利用系数为0.6。根据调查，水库下游农田主要种植单季稻，作物需水集中在69月。同时，参考广德县粮长门水库工程水资源论证报告（报批稿），其毛灌溉定额及需水量如表5-4，其需水年内分配系数见表5-5。表5-4 农田毛灌溉定额及需水量计算表灌溉面积（亩）不同保证率灌溉定额（m3/亩）不同保证率需水（万m3）50%75%90%50%75%90%2000290330360586672表5-5 广德县单季稻灌溉需水年内分配月份123456合计各月用水比重0000048.3%100%月份789101112

7、各月用水比重24.0%23.6%4.1%000（2）工业用水量经调查，分析范围内以石门卡水库为水源的企业有广德独山南方水泥有限公司。广德独山水泥有限公司取水量为96.32万m3/a。（3）生活用水经调查，该地区生活用水为自来水，不从石门卡水库取水。（4）渗漏损失量渗漏损失量包括水库对地下水补给损失和闸（坝）渗漏损失。闸（坝）渗漏损失量是指坝基、两翼及周边渗漏三部分之和。坝基渗漏一般有实测资料，其它两项可根据水文地质条件进行经验估算。没有资料一般采用按闸蓄水量的百分比进行推算，地质良好地区为01%，地质较差地区为1.53.0%。根据石门卡水库水文地质条件，闸（坝）渗漏损失量按上个旬平均蓄水量的1

8、%进行估算。（5）蒸发损失蒸发损失就是指水库蒸发损失。由于区域内没有蒸发量观测资料，故借用临近的广德气象站蒸发资料进行计算。（6） 生态需水石门卡水库建成以后，大坝下游河段减水，为保证减水段河道内生态环境用水需要，需要从水库下泄生态用水量。参考广德地区的广德县粮长门水库工程水资源论证报告（报批稿），在石门卡水库坝址断面处，河道内生态需水用2个指标进行控制：1 最小生态流量以生态基流进行控制，生态基流采用90%保证率月平均流量进行估算，对于石门卡水库，为0.013m³/s，每年下泄40万m³。2 年内生态环境总需水量以多年平均径流量的百分比进行确定，北方为1020%，南方为2

9、030%。对于石门卡水库，多年平均径流量为280.5万m³，取20%，即56万m³。因此石门卡水库日常下泄最小生态流量为0.013m³/s，年内还需另外下泄16万m³的水量，以满足河道内生态环境总需水量56万m³的要求。（7） 建设项目需水项目取水3504m3/d，项目系统年生产运行时间为330天，年取水量115.63万m3。3、 设计内容3.1 典型年选取 根据资料统计出1966年2010年的降雨量，并绘制出频率曲线如附图1，可得95%对应的数值为840.2，所以选取的典型年是1996年10月1997年9月。3.2 水库来水量计算水库的来水量
