Sampling Investigation on Inhatitant Domestic Tap Water Consumption Situation and It’s Characteristics Analysis

Economics.Through sampling investigation and analysis on inhabitant domestic tap water consumption situation,it is given that economic factors are the main factors influence inhatitant's water consumption.The functional relations among inhabitant's income and water consumption,water price and consumption are given. The tap water's income elasticity of demand and price elasticity of demand is analyzed, along with the fluctuating range month by month of inhabitant's water consumption.Finally ,this paper offers the reference data for planning the ability of water supply and making policies of ladder water prices.     

Utilizing Industry Solid Wastes as Resource of Building Material in Chongqing

To embed or heap industry solid wastes somewhere will occupy the earth and pollute the environment seriously. So utilizing the industry solid wastes as regeneration resource is important for sustainable development of city. Based on application and research for years in utilizing industry wastes and widely investigation, the produce status of industry solid wastes in Chongqing such as fly ash, desulfuration gypsum, blastfurnace slag and chromium slag are introduced. At the same time,this paper introduces application and research on these wastes in field of building material in Chongqing. Analyze problems and countermeasures during utilizing industry solid wastes as regeneration resource in Chongqing. As a further the prospect of utilizing industry solid wastes as regeneration resource of building material is discussed.     

Exploring Harmonious Protection of Land Resources in City Construction

Urbanization in China is at an essential point in its transformation from the initial stage to accelerating stage. With quick expansion of city scale and large occupation of land for urban construction, the contradiction between land resource shortage and people's living needs becomes more and more prominent. It has great affection on the grand plan of China's sustainable development of economy and society. How to adjust the relations between the development of urban construction and protect the land resource, promote the rational use of urban land, perfect and complete the protection system of land resource for improving the efficiency of urban land use. In order to conserve land resource and find a sustainable way for development of people's living and environment construction, the above mentioned problems are the most important issue for urban construction and important subject of this paper.     

Study on the Relations between Water Resource and Prataculture Development in Five Mail Pastoral Areas in China

通过对五大牧区草原区草原资源现状及其分布、草原生产力及载畜能力以及水资源现状及开发利用潜力分析,按照国民经济发展和增加农牧民收入要求,预测2010年五大牧区草原区草业发展对水资源的需求。研究结果表明,2010年五大牧区草原区农牧民人均纯收入为3400元,其中人均畜牧业纯收入2584元,需要养殖牲畜总数16413万羊单位,饲草料需求量1198.2亿kg。牧区产草总量可达1003亿kg,载畜能力13705万羊单位。尚有2708万羊单位,年需要饲料约195亿kg,需要发展灌溉饲草料地来解决,对水资源的需求量将达到

A comparative description of two farmer-managed irrigation systems in Nepal

The organization of two farmer-managed irrigation systems in the western hills of Nepal is described by examining the ways in which the activities of water allocation, water distribution, maintenance, and resource mobilization are performed. Due to the topography and environment, these two organizations are structured primarily to mobilize the large amount of labor required for maintenance of the intake and canal. Both organizations precisely define each member's water allocation. In one system, water is allocated in proportion to the area of an individual's land holding, while in the other water allocation is by purchased shares. These two cases were used to analyze the importance of the principle of water allocation for expansion of area irrigated and equity of access to irrigation. Evidence from the two systems shows that in this hill environment water allocation by purchased shares provides the individual incentive and an organizational mechanism for efficient development of irrigation resources. Expansion of area irrigated and equity of access to irrigation were found to be greater in the system which allocates water by purchased shares than where water was allocated in proportion to area irrigated.

黑龙江省江川灌区灌溉水资源的综合评价

在介绍江川灌区流域概况的基础上，提出了该灌区所面临的地下水灌溉水稻米质差、产量低、大米销路不好等问题的解决办法，即发展地表水灌溉水稻，通过引松花江水来解决灌溉水源；分别对地下水、地表水(松花江水)的水量和水质进行评价。结果表明，该灌区的地下水严重超采、水质中总铁量超标(超6mg/L)，pH值偏碱，不适合用于农业灌溉；地表水(松花江水)除铁离子略高外，其余各项指标均满足灌溉要求，为该灌区引松花江水灌溉水稻提供了较为科学的依据。     

初析农业信息资源的整合及模式

随着农业信息化的推进,农业信息网站迅速发展起来。但是问题突出,主要是各农业网站以及各级政府涉农部门的信息是一个个信息孤岛,信息资源无法共享且重复建设,信息的有效性和时效性差。为此,以黑龙江省农业信息化建设为背景,提出了加强农业信息资源整合的必要性及其模式,从而推进农业信息化“最后一公里”的建设。
