Guangxi network's electricity sources structure is not very reasonable. The built hydropower stations have not regulation capacity enough, and the thermal power generating sets have not enough peak load regulation capacity. The network's peak-to-valley defference is getting bigger and bigger. Large amounts of capacity of peak load regulation electricity are urgent needs. The construction of the pumped storage hydroplant is the optimum measurement to solve the problems such as network's peak load regulation...

Guangxi network's electricity sources structure is not very reasonable. The built hydropower stations have not regulation capacity enough, and the thermal power generating sets have not enough peak load regulation capacity. The network's peak-to-valley defference is getting bigger and bigger. Large amounts of capacity of peak load regulation electricity are urgent needs. The construction of the pumped storage hydroplant is the optimum measurement to solve the problems such as network's peak load regulation and frequency regulation. It is able to reduce abandoned water and peak load regulation electricity loss. It is also the need of the network safe and economical operation.

广西电网电源结构不甚合理,已建水电站调节能力差,火电机组调峰能力不足,电网峰谷差越来越大,迫切需要大量调峰容量。建设抽水蓄能电站是解决电网调峰、调频,减少弃水调峰电量损失的最佳措施,是电网安全经济运行的需要

Sustainable agriculture aims at that agriculture develops prolonged and continously at long time scale. It is a economically feasible and socially acceptable agricultural system in which the eco environment keeps undegradation and eco system sustains good cycling. Oasis, situated at arid habitat, is a natural social economic complex and develops depended on mountains runoff recharge. Because of its fragile eco system and humans irrational use to resources, the development of oasis is unstable and not prolonged. So, the eastablishment of oasis sustainable agriculture is the necessity in oasis agriculture development. The Gaotai Oasis in Gansu Province distributes along the middle reaches of Heihe River. The stability of its eco system affects considerably the stability of its economic system. The eastablishment of its sustainable agriculture is urgent. Oasis sustainable agriculture comprises oasis eco environment, oasis agricultural economy and oasis rural society. Thus, oasis sustainable agricultural system is constitued by agricultural eco system, agricultural engineering and technology system, and rural society system. A compromising and balance agricultural eco system, taken as the base of sustainable agricultural development, should be eastablished first of all. The contents of eastablishing sustainable agricultural eco system lie in two aspects as follows:①to eastablish stable production and living system, which includes to build hydropower stations at Yuanyang Gorge and Zhengyi Gorge for resoluting the electric power problem of oases along river, to develop solar energy and biogas, and to make full use of oasis resources. ②to eastablish improved economic and ecological system, which mainly includes to eastablish ecological agricultrue, regularize agricultural structure and efficiently make use of water soil resources; secondly, to eastablish high effective agricultural engineering and technology system; thirdly, to eastablish improved rural society system. The rural society system is further divided into natural resources information system, and social administration and service system. The natural resources information system plans resources information scientifically and provids resources information service; the social administration and service system ensures the normal operation of the whole system.

以甘肃高台绿洲为例,认为绿洲处于干旱生境中,系统脆弱,自然资源配置不佳且利用不合理,生态与经济效益低下,不利于其长期稳定的发展,持续农业是其发展的最佳选择,建立绿洲持续农业应构建绿洲农业生态系统—农业工程与技术系统—农村社会系统组成的复杂巨系统。
