Furthermore, how to apply the model efficiently in practice is deeply discussed. As the variance produced by the forecasting model as concerned, the real-time revised method of hydrological forecasting is highlighted. Next arranged, the multi-stratum recursive prediction model is put forward to forecast the error series that is a dynamic system. Later, an error selfregressive multi-stratum recursive prediction model is set up as well as a current algorithm offered. Finally, the difference collated model and the gloss control method, which are devoted to updating the mid-long term hydrological forecasting during the meditate period, are put forward.

在综合评述中长期水文预报现有方法和模型的基础上，采用时间序列分析方法，建立中长期水文预报的时间序列组合模型，并对模型如何在实际中有效应用作了较为深入的探讨；针对模型预报所产生的误差，又重点研究了水文预报实时修正方法：提出了采用多层递阶预报方法对误差序列这一动态系统进行预报，建立了误差自回归多层递阶预报模型，并提出了较为通用的解算方法；给出了水文中长期预报中期修正的残差相关模型和总量控制方法。

Under coaction of endogenic geological processes and water and heat conditions, the drainage development, and water formation and transformation in the inland watershed. were indicated hydrological characteristics of periglacial zone. The hydrological process is mainly related with to changes in mountain areas. It by 41% of precipitation in mountain areas as surface discharge flows into middle and lower reaches, which makes up a main physical basis of the quantitative and qualitative relationship for various functional units in the eco-system in mountain front plain.

加强水文水资源监测站网的规划，加快水文测报现代化建设，提升水文水资源预报能力，大力开展长江水文水资源变化规律研究，促进水文事业发展，是长江水文的发展方向。

This region has been put fourth regional groundwater resource evaluation from year 1956 to 2002. These evaluation all take Quaternary groundwater resources as exploited study objectives, evaluate plains and montanic groundwater separately, didn"t consider overall portray groundwater hydrological system relation between input and output, couldn"t simulate groundwater hydrological process with circumstance fluctuation. Therefore, it"s necessary to reevaluate Sanjiang Plain"s groundwater resources on the basis of predecessors study.

该区自1956年至2002年主要进行了四次区域性的地下水资源评价工作，这些评价均以第四系地下水资源为研究对象，以开发为目的对平原区和山丘区地下水资源分别评价，没有考虑全面刻画地下水文系统输入输出的转化关系，无法模拟变化环境下的地下水文过程，因此，有必要在前人研究的基础上，重新评价三江平原地下水资源。

In hydrological modelling one of the most common and significant challenges faced is the reduction of uncertainty in estimation and calibration of model parameters,especially how to estimate parameter values for ungauged basins and simulate the hydrological effects of basin development scenarios and water usage practices.

目前应用较为广泛的模型多为集总式模型。但是，集总式水文模型有很多缺点，如不能反映实际暴雨洪水产汇流的空间分布特性，无法全面的刻画水文系统分散输入集中输出的产汇流规律等。因此为了研究和解决变化环境中的水文水资源问题，评估和检测流域的径流过程和水资源量的动态变化规律，实现水资源的可持续利用和发展战略，必须开发研制有物理基础的分布式流域水文模型。
