【摘要】：气候变化和高强度的人类活动对水文循环及其时空演变规律产生了重要影响,原有研究成果已不能真实反映现代条件下的水文变化规律。作为概念性模型的代表,新安江模型已不能适应变化环境下流域综合水文要素的模拟,因此有大量应用基础研究工作亟需加强。为解决这一难题,文章以新安江水文水资源实验站改建项目为例,阐述嵌套式强化观测流域设计方案的应用,在原有设施基础上,嵌套增建了原型小流域及坡地水文综合要素观测场、嵌套式强化观测流域、水文综合实验与分析测试中心及远程接收中心。结果表明该设计方案能够有效的提升数据资源类型及涵盖面,为发展新一代水文模型系统提供数据支撑,为建设流域大气-水文-生态综合模型提供科学依据。
[Abstract]:Climate change and high intensity human activities have an important influence on the hydrological cycle and its temporal and spatial evolution law. The original research results can no longer truly reflect the hydrological variation law under modern conditions. As the representative of conceptual model, Xinanjiang model can no longer adapt to the simulation of integrated hydrological elements in the changing environment, so there is a large number of basic research work in need of strengthening. In order to solve this problem, taking the reconstruction project of Xinanjiang Hydrological and Water Resources Experimental Station as an example, this paper expounds the application of nested intensive observation watershed design scheme, based on the original facilities. The prototype small watershed and slope hydrological integrated elements observation field, nested intensive observation basin, hydrological comprehensive experiment and analysis and test center and remote receiving center were built by nesting. The results show that the design scheme can effectively improve the data resource types and coverage, provide data support for the development of a new generation of hydrological model system, and provide scientific basis for the construction of the integrated model of atmospheric hydrology and ecology in river basin.
