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     

福建省甘薯种质资源鉴定与评价

征集甄别保存甘薯种质资源606份,编写出品种目录,拍摄了彩色图谱册;摸索出适合福建省气候特点的田间种植、薯块贮藏、老蔓越冬和茎尖脱毒试管苗4种方法相结合的安全保存方法;首次在相同条件下同时完成了对保存的品种资源抗蔓割病、薯瘟病的鉴定,8种主要营养成份的分析及鲜薯与薯干产量的测定,筛选出抗蔓割病资源212份、抗薯瘟病资源109份、高干率资源14份、高淀粉资源12份、高水溶性糖资源13份、高粗蛋白资源13份、高粗脂肪资源12份、低粗纤维资源12份、高维生素C资源12份、高胡萝卜素资源12份,初步摸清了这些品种的分布情况;应用Borlanddel-phi7.0为设计集成环境和通用SQL方式查询程序模块创建了资源数据库;建立了107份骨干资源圃。     

污泥农用资源化研究现状

污泥中富含N,P,K及有机质,是天然的有机肥料。因此,污泥的农用是污泥处置的最佳途径。污泥农用的主要途径有农田施用、林地施用、研制复合肥以及作为土壤改良剂。为此,结合实例阐述了我国污泥农用资源化处置现状及未来发展趋势,并指出了污泥农用的发展方向。     

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.     

农机服务体系建设中的资源整合

在农机化的快速发展过程中,农机资源本身也需要以更多的实现形式进行平衡的资源优化配置和整合,以更好的投入产出水平发挥它在农业生产、加工中的作用,适应未来农机服务市场的变化.     

马鞍山市向山垃圾填埋场抽气实验研究

本文根据马鞍山市向山垃圾填埋场的现场抽气实验，分析了影响垃圾填埋气体产生的各因素的变化规律，确定了抽气压力、气体流量和甲烷含量的关系及其影响因素，并以此为基础对填埋气体收集利用工程中填埋场的选择和系统的设计提出了建议。     

水井酸处理效果预测研究

水井酸处理效果预测一直缺乏成熟的方法。提出了根据水位恢复曲线形态和含水层裂隙特征来预测井的首次酸处理效果，经与石油界所用方法有明显不同。石油界普遍认为，只有不位恢复曲线为快速上翘型的低产碳酸盐岩井才适合酸处理（即基质酸化），但作者近年来发现，多数水位恢复曲线为直线型的低产碳酸盐岩井，即井中含水层裂隙平均宽度＜5mm的井，酸处理效果也很好，被调查3眼这类井的单位涌水量增加值平均为423％；水位恢复曲线为缓慢上翘型的井中，部分含水层裂隙被松散物充填的井，采用特殊的酸处理方法处理后，井的单位涌水量可增加100％。另外，采用适当的方法，使用足够数量的酸进行首次酸处理后，水井再进行酸处理一般效果都很差。
