多年冻土区第一井——舍尔金井

The first well in permafrost regions: Shergin Well

舍尔金井位于俄罗斯东西伯利亚萨哈共和国雅库茨克市中心,总深度为116.5 m,是多年冻土区第一口深度超过100 m的井。井的挖掘从筹划到完工(1837年)历时10年,是俄罗斯商人费多尔·舍尔金(ФедорШергин)为挖井取水而建造的。舍尔金井的温度资料无可辩驳地证明了多年冻土的存在,它不仅是重要的文化和历史遗产,还是多年冻土存在的重要证据及冻土学发展的见证。

In this paper, by introducing the theory of supermodular game into the analysis of fiver basin water resources management systems, the external environment constraints and internal incentives in the execution of river basin water resources management policy are explained and the relation between management domain and external domain is described through the model describes. It is found that there is a paramount role of the super-modular structure in the game of water resources in the Qiantang River and Heihe River basins. In the Qiantang River basin the revenue function of the water resources management has an increasing difference between institution governance variable and economic domains governance variable. In the Heihe River basin the revenue function has an increasing difference between water resources management institution governance variable and social domains governance variable. Thus, regional heterogeneity engenders. Specifically speaking, the Qiantang River basin water resources management focuses on flat and functional management; the Heihe River basin is water resources hierarchical allocation. Finally, depending on the study results, some institutional suggestions are put forward.
