| | It is thought that the Yangtze River turning into the Yellow River is indisputable, that the consequence of which would be much more serious than that in loess plateau if it is not controlled promptly. Today, naked mountains and bare hills are expanding swiftly and violently, making the rich soil having been formed in several hundred thousands years the poor naked land, drought and flood disaters occuring alternatively, land slides and debris flows being frequent and severe, sediment deposition makes reserv... | | 根据长江中上游水土流失程度,长江变成黄河已是无可辩驳的事实;如果不立即防治,其后果比黄土高原严重得多。目前,光山秃岭迅猛发展,使几十万年形成的沃土变为不毛之地;旱灾和洪灾交替发生,滑坡和泥石流频繁而严重;淤浅水库和河床,妨碍交通航运;广大人民生活贫困,部分灾民靠救济为生。综合治理,尽快改变现状,脱贫致富,希望很大。主要对策有:1、用生态经济的系统工程,治理长江中上游的水土流失;2、营造防护林体系工程,恢复和扩大以森林为主体的生态系统;3、抓住重点,培养样板;4、加强科学研究工作,充分发挥其先导作用。 | | 文摘来源 | | In this paper based on the theory of elastic half-space and dynamic analyticalmodel, a generalized Dunkerley-Southwell's formula is derived from the charac-teristic equation of structure-foundation system. The formula presented hasthe advantages of overcoming the limitations of the available Dunkerley-South-well's formula as well as taking into account the effect of foundation embed-ment, mass and rotational inertia of foundation, and coupling effect of trans-lation-rocking motion. This leads to more ration... | | 本文基于弹性半空间理论及所采用的动力分析模型,由结构-地基体系的特征方程出发,推导出结构-地基体系的Dunkerley-Southwell公式。它克服了原来Dunker-ley-Southwell公式的局限性,考虑到结构基础埋置深度、基础转动惯量、基础质量及平移-旋转运动的耦合效应等因素,能更合理地反映结构-地基体系的工程实际。本文公式尚可推广应用于结构-桩-地基体系基频的计算。该公式不仅计算简捷,且计算结果具有较高精度。 | | 文摘来源 | | The forestry construction during last 40 years in China has been briefly summarized, with special introduction to the construction of five main forestry ecological projects, which arc Northeast, Northwest and North China shelter-forest system; middle and lower reaches of Changjiang river shltcr-forest system; coastal area shelter-forest system; plain forcstation and Taihangslxm mountain area afforestation.
