While expanding deep - sea fishing and international fishing cooperation , china adheres strictly to relevant international maritime laws , pays full attention to protection of the eco - environment and , in the light of the principle of " equality , mutual benefit , rational development of the exploitable resources , and abstention from infringement on the interests of other countries , " actively develops fishing cooperation with relevant countries and regions , in order to jointly expand the fishing economy 中國發(fā)展遠洋漁業(yè)和國際漁業(yè)合作,本著嚴格遵守有關國際海洋法,并充分注意保護生態(tài)環(huán)境,在平等互利、合理開發(fā)可利用資源、不損害別國利益的原則基礎上,積極開展同有關國家和地區(qū)的漁業(yè)合作,共同發(fā)展?jié)O業(yè)經(jīng)濟。
In order to find out the exploitable potential of water saving , quantitative analysis was employed in the researches on the supply - demand balance of water resources in qyrid . under the condition that the water supply from the yellow river is becoming less , it is recommended to reduce the water use in agriculture through the adjustment of cropping structure and to exploit the underground water for supplementary resources 為了定性分析青銅峽灌區(qū)可挖掘的節(jié)水潛力,本文通過分析研究灌區(qū)水資源供需平衡問題,提出在黃河可供水量緊缺的情況下,通過調(diào)整農(nóng)業(yè)種植結構、減少農(nóng)業(yè)用水、開采地下水和增加水資源供給量來解決灌區(qū)水資源供需矛盾。
To maximize potency of exploitable land surrounding guogongzhuang station , to drive intensive and effective utilization of land , and enhance comprehensive returns on both rail transit and land surrounding the station , by developing of above underground and integrating and harmonizing of the station and surrounding land ; and through introducing advanced design idea , to create human - oriented , safe , fast , convenient and effective public transportation , and improve environments of transit 挖掘車輛段用地和郭公莊站周邊可開發(fā)土地的效益,通過上蓋開發(fā)及車站周邊土地與車站的協(xié)調(diào)整合,促進土地的集約高效利用,提高軌道交通和周邊土地的綜合效益;同時,通過引進先進的設計理念,創(chuàng)造以人為本的,安全、便捷、舒適、高效的公共交通條件,完善換乘環(huán)境。
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 最后,通過數(shù)值法反復調(diào)算計算出本區(qū)地下水的允許開采量,計算結果表明,在現(xiàn)狀開采的條件下,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。
Based on successive regression study of observation data , the authors ascertained the factors having influence on the fluctuation in the bai spring discharge , established the regression equation and the prediction model , and calculated the exploitable karst water resources under natural conditions 摘要本文通過對輝縣自泉泉水流量動態(tài)的分析,確定了泉水流量動態(tài)的影響因素,建立了泉水流量的衰減方程和泉水流量的預測模型,預測了天然狀態(tài)泉水流量,評價了泉域巖溶水的開采資源。
