  1. The results are as follows : ( 1 ) if we increase the pumping water by 493 x 104m3, the amount of leakage recharge of rubber dam will rise by 231x 104m3 ; which indicates pumping by rubber dam can excite much more surface water infiltrate so as to supply groundwater. thus the utilization ratio of water source is increased, and it provides the reliable guaranty for enough supply of the groundwater storage in wet year. ( 2 ) under the condition of present status, the groundwater exploitable resource in wet year is 3670 104m3

    最後，通過數值法反復調算計算出本區地下水的允許開采量，計算結果表明，在現狀開採的條件下，大沽河地下水庫豐水年（ p = 20 ）時地下水允許開采量為13670 10 ~ 4m ~ 3 ，平水年（ p = 50 ）時地下水允許開采量為12054 10 ~ 4m ~ 3 ，枯水年（ p =加% ）時地下水允許開采量為10951xl了砰。
  2. The results show that after reaching relative stableness, the dam system located in the region is able to supply 1. 6 - 2. 9 billion m3 of water for agriculture. most annual runoff in approximately half of years can be stored and utilized, and the replenished soil moisture is 5. 2 billion m3 above in more than half of years

    結果表明：河龍區間在壩系達到相對穩定后，通過壩系的攔蓄作用，每年可提供16 29億m ~ 3農業用水；有47的年份年徑流大部分可被攔蓄利用；有53的年份壩系土壤水分補充量可達52億m ~ 3以上。
  3. The second stage of the uprating engineering works were implemented after the signing of the agreement in august 1979 endorsing the planning report for the second stage extension of the dongshen water supply system. the main works were to extend the pumping facilities at matan, tongxia, zhutang, shaling, shanpu and yantian, and to increase the height of the main dam of shenzhen reservoir by 1 metre. the new works included the construction of a new pumping station - the dongjiang pumping station at the intake point at the riverbank of dongjiang to increase the volume of supply

    第二期工程於1979年8月簽訂《東江深圳供水工程第二期擴建規劃報告》協議后進行，主要是再擴大原工程在馬灘、塘廈、竹塘、沙嶺、上埔及雁田的抽水站，加高深圳水庫主壩1米，新建的工程則包括于新開河口興建東江抽水站，提高供水數量。
  4. The following three alternatives are used to assess the impact caused by the projects, ( l ) the entrance of tunnel is at the downstream of the huanren dam and the main purpose of the huanren reservoir is to supply water for the project, ( 2 ) the entrance of tunnel is at the downstream of the huanren dam and the main purpose of the huanren reservoir is hydropower generation and ( 3 ) the entrance of tunnel is at the upper of the huanren dam

    本文擬研究該調水工程的水源工程?桓仁水庫的調度運行方式，使工程的正面效益較大，負面損失盡可能地小。桓仁水庫的調度方式有三個方案： （ 1 ）以供水為主的壩下取水方案； （ 2 ）以發電為主的壩下取水方案； （ 3 ）庫區取水方案。
