In general, the hydraulic risk is not considered in most of the hydrological analysis in floodproofing plan and design. In this paper, a method of evaluating the hydraulic risk is developed by employing risk theory, and the concept can easily be extended to other types of risk analysis. As a result, it is possible not to consider the hydraulic resks when the design hydrologic risk of flood control dam is lger. Otherwise, the hydraulic risks must be noticed. The research is very helpful for the development of the flood control theory used at present.展开更多

However, China＇s sustainable agricultural development faces severe tests such as agri-tech ＂short slabs＂ and poor collaborative operation. The 12＇h Five- year Plan period will bring both strategic opportunities and challenges. Brisker market demands and more agricultural inputs, a higher technical level and better policy regimes will drive development. On the other hand, agriculture will be confronted with more resource and environment constraints, fewer traditional comparative advantages and hidden hazards, etc. Over the next five years, China should stay its course to agricultural modernization based on its national conditions and the sustainable development concept and establish a ＂broad interpretation of grain security＂ to improve the productivity, risk- resistance capabilities and market competitiveness of its agricultural industry.展开更多

However, the important problem existing presently is that the significance of the financial management is mostly ignored in the small and micro-sized enterprises, pursuing the short-term economic benefit blindly, which decreases the risk resistance of the small and micro-sized enterprises severely, so that a mass of the small and micro-sized enterprises with poor survivability and extremely short life cycle are occurred. This text analyzes the problems existing in the financial management of the small and micro-sized enterprises around the above several prominent problems, and discusses the corresponding suggestions to promote the sound development of the small and micro-sized enterprises in our country.展开更多

We find out the critical point and the critical line of the break-everL We analyze the ability to resist risk. This analyses help the micro agricultural project＇s investors to price reasonably, forecast the earnings and make the correct decision.展开更多
