The effects of friction in surface layer on the structure of front and the frontogenesis in boundary layer, the interaction of orographic disturbance with front, the influence of diabatic process and moist process on the frontogenesis are investigated. Second, the occurrence and development of frontal rainbands have been studied extensively through the observational and theoretical approaches near half-century. However, there are still some problems needing further investigations because of the complication of the precipitation process.

Based on the Saint-venant equations describing the channel flow movement, the nonlinear algebraic equations derived by the use of Preissmann weighted implicit four-point scheme are solved with the Netwon-Raphson method. A combined Gauss main-element elimination method with compress-storage technique is proposed. The relaxation iterative method for solving branch river networks is extended, which can turn the problem of any complex river networks into the problem of a series of single rivers. The coupling of hydraulic model with water quality model is built up. The combined model was applied to a large complicated river networks with numerical hydraulic structure which influenced by strong tide, storm and heave rain. Visualization of computational results is realized by means of MapInfo, which displays the computational results in fast, convenient and accurate way.

The four well-known skeleton hydro-power stations of West-East Electricity Transmission Project, named Xiangjiaba, Xiluodu, Baihetan and Wudongde from the lower reaches of Jinshajiang River to upriver reaches, are all distributed in this area. Based on the analysis of the resource exploitation and industry sustainable development status, current problems and future scenarios, the main conclusions go as follows:(1) There are abundant and varied agricultural resources, widely distributed mineral resources with valuable predominant minerals, potential tourism resources, but some main problems such as lower level of exploration and development, serious waste and pollution, restraints of financing and transportation and eco-environmental frangibility still call for immediate solution;(2) Regional economy develops fast but the overall level is low-farming and animal husbandry industries, In which crop-plantation takes the main part, dominates in the sectional structure of economy, and forestry and specialty industries need to be further developed. The existed restraints such as unbalanced structural and regional economic distribution, acute structural deficiency and low economic efficiency need to be cleared out, of the way to a sustainable future.
西电东送骨干工程的向家坝、溪洛渡、白鹤滩、乌东德四大水电站均分布在这一江段通过对该区域资源开发和产业发展的现状、问题和发展前景进行分析,得到如下主要结论:(1)该区域农业资源丰富多样,矿产资源分布广泛且优势矿种地位突出,旅游资源待开发潜力巨大,但是资源开发却面临着勘探开发程度不够、浪费污染严重、资金交通制约和生态环境脆弱等几大问题;(2)区域产业经济发展迅速但总体水平低,部门结构中以种植业为主的农牧业占主导,林牧业和特色产业有待进一步开发,产业发展面临着部类和区域不均衡、结构矛盾突出以及效益低下等问题的困扰。
