Study on the Construction Quality Assessment System

A model of "construction quality assessment space" is designed in this paper,which illustrates construction quality assessment in three aspects as construction types,phases and characteristics.Based on this model,the construction quality assessment system(CQAS) is structured.As a part,the construction quality index(CQI) can be used for evaluating the Chinese construction quality status;and some technical methods such as spot checks and analytic hierarchy process can be used for getting macro and micro construction quality assessment results.     

Landscape Construction of Urban Waterfront Environment

Urban waterfront landscape is the most vital landscape form in a city, the most quality urban green line, and also an ideal habitat corridor. Urban waterfront landscape belt has inborn lasting attractiveness for urban citizens. Considering needs of urban development, development and redevelopment of waterfront areas have been initiated in many cities to meet relaxation and leisure needs of citizens. This paper analyzed landscapes of urban riverfront environment, embankment landscape engineering, and waterfront plant cultivation, so as to further explore landscape construction of urban waterfront environment.     

Landform Design of Urban Landfill Landscapes

Compared with landform design in common urban green spaces, landform landscape design of garbage landfi ll sites require higher technical regulations, and there are more restrictions for the design. This paper explored landform design of three types of landfi ll sites: domestic garbage landfi ll site, building waste landfi ll site and polluted soil landf ill site. Two aspects were included: exploring landform peculiarity of landfi ll sites by sorting out technologies and regulations; exploring landscape design methods of landf ill landscapes.     

Flexible Design Methods of Urban Waterfront Areas

Waterfront area is always a central district in a city, and favorable designs improve taste of the city. With the further urbanization and improvement of living standards, design of waterfront area has to meet not only needs of water conservancy and flood control, but also psychological needs of users. Using flexible design principles and methods, urban waterfront areas will be more flexible and capable of adapting to changes of neighboring environment.     

Renovation of Flexible Landscapes in Urban Brownfield Sites

By analyzing realistic problems of urban brownfield site, this paper combined flexible design and renovation of brownfield landscape renovation, and proposed suggestions for the flexible landscape renovation of urban brownfield sites, so that renovation of urban brownfield landscape is not confined in renovation, but is more flexible and adaptive, and flexible design is positive for the renovation of urban brownfield landscapes.     

Settlement of Index System on the Aged Life of Quality

This paper establishes the index system of aged life quality and confirms index system weighea from AHP according to connotation of aged life quality through comparison between the population aged of quality and the aged. life of quality. The authors offer operation basis so as to judgement and improvement of the aged life of quality.     

Construction of Trail Tourist Attractions Assessment Index System

Based on the further analysis of trail's concept,trail tourist attractions was proposed as a new concept,and the 5-dimension(trail resource,trail operation,trail technology,trail management and trail economic index) theoretical assessment framework for trail tourist attractions was established. Trail route selection,trail pavement and trail management grade were taken for example to explain the specifications for these secondary indexes. The future research should expand the index system to cover all secondary indexes of the 5 dimensions,put the concept of trail tourist attractions into tourism planning practices,and provide examples for the construction of trail tourist attractions across the country. Proposal of the concept of trail tourist attractions and its assessment standards is an attempt and innovation in the development of scenic areas,and will possibly result in the new development rules of scenic areas.     

A Proposed Index for Assessment of Row-replacement Intercropping System

A new index has been proposed for assessing an intercropping system where the component crops are in row replacement senes. It determines the Actual Yield Loss or gain (AYL) in respect to a component crop in an intercropping situation Here the sown proportion of the component crops with regard to its sole one is to be considered. This index appears to be more appropriate than other established indices like land equivalent ratio, relative yield loss, etc., particularly when per plant yield is considered. Partial AYLs (which are the two components of this index) can be considered as indicators regarding the competition existing between the component intercrops.     

Planning Overall Landscapes,Building a Garden City:on the Revision of Guangzhou Urban Green Space System Planning

The concept of urban green space system planning was proposed after analyzing the background of compiling Guangzhou green space system planning and current situation of local green spaces,i.e. design landscape pattern of Guangzhou City during urban agglomeration of the Pearl River Delta,and highlight Lingnan cultures(Lingnan refers to south of the Five Ridges) and features of Flower City(another name of Guangzhou). Key points of planning are protecting ecological barriers in the north,improving urban garden structure in the center,using wetland reasonably in the south,to maintain integrality and continuity of the landscape pattern.     

基于城镇分等指数调控的基准地价平衡研究

为真实反映城镇空间差异与城镇基准地价变化的特征,笔者运用比较法、特尔斐法、加权求和法等,以分等指数控制城镇等级,将同一水平城镇归于同一等级区间,确定不同等级城镇的基准地价变动幅度,实现以指数控城镇,以等级调价格。结果表明：在新乡市域内,一等城镇包括辉县市、卫辉市、新乡县、延津县;二等城镇包括获嘉县、原阳县、封丘县;其中一等城镇商服用地和住宅用地的一级地价格在890~1215 元/m²和650~880/m²;末级地300~410 元/m²和260~350 元/m²,二等城镇一级地在750~840 元/m²和520~575/m²;末级地在300~330 元/m²和220~250 元/m²,即城镇等级越高,其同用途同级别的地价也越高。     

An Evaluation Method for the Quality of Urban Hot Environment - Air Total Heat Change Quality Index

Due to the effect of hot island of the city, the temperature is much higher and the urban hot environment is much worse in the city than those in the countryside. In this paper, the total heat difference based on the temperature has been suggested as an evaluation factor and the total heat change quality index as evaluation method to describe the quality of urban hot environment.     

环渤海现代农业指标评价体系的构建与发展水平评价

为明确环渤海区域农业发展水平,以加快区域现代农业发展进程,以现代农业综合发展水平为评价总体目标,以农业投入、农业产出、农村社会发展水平及农业可持续发展水平为分级指标,构建了环渤海现代农业区域发展水平评价指标体系,并对以市为基本评价单元对环渤海区域现代农业进行了评价。结果表明：环渤海区域的综合发展水平为0.585,刚进入现代农业发展阶段。分地区看北京最高,达到0.798,其次为天津0.694、山东0.644、辽宁0.606,河北最低,为0.595;分城市看,环渤海区域现代农业目前还没有任何一个城市达到发达阶段的水平,处于初步实现阶段有10个城市,主要集中在山东（占5个）,其他大部分城市还处于起步阶段和发展阶段。

黑龙江省黑土地质量评价指标体系构建

黑土地是肥力较高、适合进行农业耕作的土地,作为全国第一的黑土地大省,由于土壤侵蚀和长期高强度重用轻养等原因,黑龙江省出现了黑土流失、地力下降等问题。研究旨在建立黑土地质量评价指标体系,为评价黑土地质量等级,继而采取不同的保护措施提升黑土地质量提供依据。为突出黑土地特征,考虑代表性、易获取等原因选取了4个一级指标及23个二级指标构建黑土地质量评价体系,并提出黑土地质量综合评价指数,识别各种土地利用类型下的土壤质量等级。研究结果表明：选取土壤厚度、土壤养分、土壤酸碱度和土壤侵蚀作为一级评价指标,黑土层厚度、有机质含量、全氮含量、全磷含量、pH等作为二级指标,利用黑土地质量综合评价指数,可以较好评价黑土地质量的改善或恶化情况,从而确定黑土地质量等级;运用该指标体系和评价方法跟踪黑龙江省黑土地质量变化趋势,可为评价各种保护措施的实施效果和落实情况提供科学的依据。
