Model of Information Integrating in CIMS Based on the Object-oriented Method

Information integrating is the most important key to CIMS,which is the base of the function integrating and all others.Because of so many kinds,so complicated structure,so many different sources and uses that the information in CIMS has,it is necessary to build a popular Information Integrating Model. The model of information integrating in the thesis bases on the enterprise model,which is presented by ISO(International Organization for Standardization).According to the object-oriented method,the process of modeling begins with classifying the information,and then describes the definition of the attributes and the structural relation of those objects. By means of the idea of Encapsulation and Inheritance,the destination of information integrating can be arrive and the model of information integrating can be set up. The model which is based on the share information is helpful to finish the function integrating and the whole CIMS' construction. Moreover,the system which is developed following such program can be reused for many times and the developing circle of CIMS can be apparently shortened,too.     

Optimum Planting System for Energy Saving and Healthy Demanded

It is proved that planting is effective to improve environment both indoor and outdoor resulted from the functions of plants to clean air and save energy. So the contradiction between saving energy and comfort,healthy demanded by people can be solved by planting. The planting have being emphasized and expanded during recent years,but in the planting plan,just the function of beautifying the environment is concerned and the function of ecological and saving energy are neglected. The analysis on the ooptimum system of planting is to make the planting system as an organic composition in the effectiveness structure and space layout of the city. Based on the study on equivalent relation of different effects on environment, the optimum system of planting structure will be determined in order to achieve the integrated effects of planting on environment.     

A Research of Life Cycle Integrated Management Pattern of Construction Project

Development Management (DM) in decision phase, Project Management on behalf of the owner (OPM) in implementation phase and Facility Management (FM) in operation phase are three isolated management tools during traditional life cycle management of construction project. As a result, a lot of potential disadvantages are aroused. In recent years, many research organizations try to reform the traditional method using different integration means. This paper tries to explore into integration of DM, OPM and FM to overcome the malpractice of traditional life cycle management of construction project. The research focuses on three aspects: 1.putting forward the concept of Life Cycle Integrated Management (LCIM), based on management integration theory; 2. Raising a new idea to owner's (operator's) management organization design, which emphasizes on the balance of life cycle objectives; 3. Analyzing an information module, level and method of system integration of Life Cycle Integrated Management Information System.     

南方涝渍地综合整治开发效果的评价研究

以 2个示范区作为实例构建了一套对南方涝渍地实施以农业工程技术为基础的综合整治与建设后的效果进行评价的评价体系。该体系由工程效果、农业综合开发效果和综合效益等 3部分构成。在工程效果评价中 ,重点对工程实施后的抗灾减灾效果和代表经过改良后农田物理构架改变的“农田综合生产力指数 (IPI)”等二方面进行了分析。研究表明 ,该评价体系能比较全面、有重点地对涝渍地综合改良的实效做出评价。由于该体系实现了评价的数量化 ,使用该评价体系既利于对同一地区改良前后的效果做出对比分析、找出存在的问题 ,也利于对邻近不同地区的改良效果做出比较评价。对 2个示范区进行实际评价的结果表明 ,该地区的涝渍地综合整治开发效果良好 ,其第一期工程取得成功。

基于APSIM模型的旱地春玉米施肥类型及氮肥用量研究

为探究玉米高产和减少硝态氮残留的合理施肥模式,通过山西寿阳旱地春玉米田间试验和APSIM模型模拟,研究不同施肥类型和施氮量对春玉米产量、硝态氮残留量和氮肥利用率的影响。田间试验设置3个施肥类型主处理,包括化肥单施、有机无机肥配施（配施比例1∶1）和有机肥单施;7个施肥梯度副处理,分别为0、50、100、150、200、250、300 kg·hm^-2,并利用2019—2021年试验站点数据对模型进行校准验证。结果表明：APSIM模型可以较好地模拟当地玉米产量和硝态氮残留量状况。各降水年型下,随氮肥施用量的增加,玉米产量先增加后减少,硝态氮残留量显著增加,氮肥利用率有所降低;相同施肥类型及施肥量下,丰水年的春玉米作物产量最高,硝态氮残留量最低,氮肥利用率最高;相同降水年型及施肥量下,有机无机肥配施方式的春玉米产量最高,硝态氮残留量居中,氮肥利用率最高。相较于化肥单施和有机肥单施方式,有机无机肥配施对于干旱地区玉米产量提升效果更好,其土壤硝态氮残留量对降水变化的敏感性相对较低,其氮肥利用率受降水影响也更小。综上,当施氮量介于148~168 kg·hm^-2时,有机无机肥配施方式下土壤硝态氮残留量维持在阈值内,春玉米产量可达到理论产量的95%左右,适宜在研究区域推广应用。
