At Guinea the gold 迪 is second, the section 巴 wait the main 产 area, expert of ground paddy rice in the headwaters than good, rich soil of local chose 6 demonstrates the point, and demonstrate to plant the area 7.4 hectares, demonstrate the point most press be ground cultivation method proceeds, then not apply fertilizer the 料, not the 施 agrochemical , Chinese 杂 hand over the 稻 to express the familiar period more early, yield increase by 1 times above.2004 the dry quarter, expert organize in the section 巴 big area of farm demonstrate, the demonstrate plant the area 130 average and each hectare of hectares, single 产 5.02 ton, create Guinea big area of paddy rice produce tallest record.

在几内亚金迪亚、科巴等地水稻主产区，专家在水源较好、土地肥沃的地方选择了6个示范点，示范种植面积7.4公顷，示范点多数按当地栽培方法进行，即不施肥料、不施农药，中国杂交稻表现熟期较早，产量增加1倍以上。2004年旱季，专家组织在科巴农场大面积示范，示范种植面积130公顷，单产平均每公顷5.02吨，创几内亚水稻大面积生产最高纪录。

This part includes deep analyses of different costs and corresponding compensation policies for Miyun reservoir water resource reserve.

In multi-source pipe networks, if the treated water qualities vary greatly, with a large difference in residual chlorine decay rate coefficient, it will cause errors.

对于多水源管网而言，若各出厂水水质差别很大，而使余氯衰减常数相差很大时，将造成误差。

This paper presents a new chlorine decay model adaptable to the real multi-source network, using Epanet-msx simulation module, comparing the differences in the concentration of chlorine caused by using the same or different chlorine decay rate coefficient of the treated water from different water plants, and then taking the discrepancy of the chlorine decay rate coefficient into consideration will be able to reflect residual chlorine concentration and changes in the network more realistically.

通过建立符合实际工况的多水源余氯衰减模型，运用Epanet-msx水质模块进行模拟运算，对比不同水厂余氯衰减系数同一化处理和差异化处理对管网余氯浓度造成的差别，可以看出差异化处理将能更真实地反应管网中余氯浓度的分布和变化情况。
