保障性住房适建性评价及其空间区位选择——以杭州为例

通过对研究现状述评与保障性住房建设问题的分析,发现不恰当的居住空间区位分布直接导致了保障性住房效用发挥的低下。区位选择的本质也即适建性评价。结合民意调查,发现保障性住房有3个主要影响因素,通过技巧性的评价路径设计,论文对各影响因子进行了详细的度量分析,并基于"好区位的认定标准"与"三因素综合原则",提出了多因子叠加的保障性住房适建性评价方法。最后在评定结果基础上,指出了杭州保障性住房区位选择的发展策略。

存量发展下城市工业区增绿节地式发展研判——以上海典型产业园区为例

存量发展下,为应对工业用地产出绩效和环境品质的双重提升压力,屋顶绿化成为产业园区升级改造中提升环境品质的有效途径。文章构建适宜产业园区应用推广的草坪式屋顶绿化的适建性评价体系,选取上海典型的优化类及转型类产业园区为研究样本,评估样区内屋顶绿化的适建情况;进而将适建屋顶绿化面积折算成可增加的地面绿地率,评估园区环境品质的提升潜力。结果表明,产业园区适于推广建设屋顶绿化,不仅能够提升园区环境品质,而且可适当置换获得用地开发指标增量收益。

Study on Urban Construction Land Suitability Evaluation in Southwestern Mountainous Areas of Yunnan Province Based on the Strategy of "Protecting Farmland in Flatland Areas and Constructing Mountainous Cities" : A Case in Lianghe County

According to the particularity of towns＇ construction in the southwestern mountainous areas of Yunnan Province, this study has built constructive land suit- ability evaluation index system which is different to flat area. Then this study deter- mined single evaluation factors index and comprehensive suitability index using ＂ex- treme conditions method＂ and ＂suitability index method＂, and analyzed and assessed the constructive land suitability on each evaluation unit polygons and its suitability level by using GIS software. Taking Lianghe County of Dehong Dai-Jingpo Au- tonomous Prefecture as an example to evaluate land suitability in Lianghe County＇s main towns around the gentle slope, the results show, in the evaluation area, the area of land suitable for construction and unsuitable for construction respectively ac- count 73.58% and 26.42%. And first-class, second and third-class of land suitable for construction should be composited at the ratio of about 11：49：40. The suitability evaluation index system and method developed in this paper is applicable for evalu- ating the construction land suitability in mountainous areas of southwest Yunnan Province, and will provide theoretical and technical support for land policy measures which strengthen the protection of farmland and promote the scientific development of urbanization in Yunnan Province and even similar mountainous areas of the whole China.

Urban Construction Land Suitability Evaluation Based on Improved Multi-criteria Evaluation Based on GIS(MCE-GIS): Case of New Hefei City,China

Urban construction land suitability evaluation （UCLSE） is a complex system engineering and the basis for rational use of the limited urban land resources in China. It has an important practical value on urban construction land use planning and management from the angle of methodology. As a widely used technique, traditional multi-criteria evaluation based on GIS （MCE-GIS）, is not suitable for UCLSE. This study develops an improved MCE-GIS method which could be more suitable for UCLSE based on urban complex ecological system theory and the summary of the shortcomings of traditional MCE-GIS. The improvements include three aspects： a composite evaluation index system rather than natural indexes alone, an index weight calculated by using fuzzy Analytic Hierarchy Process （AHP） method rather than the common AHP method, and the integrated overlay rule, which includes selecting the minimum value, weighted linear combination （WLC） and simple summation. The main advantage of this improved technique is that it can make UCLSE more comprehensive, more operational and more reasonable. It can provide a scientific basis for decision making in the planning and management of urban construction land use. The improved MCE-GIS system has been adopted in the New Hefei City, Anhui Province, China. Based on the results of UCLSE in New Hefei, three functional areas including construction-appropriate areas, construction-restricted areas and construction-forbidden areas could be worked out, in which 36.90% of the total study area could be developed as urban construction land and the remaining 63.10% should be protected as reserves land or as ecological land. Furthermore, the results can orovide scientific decision suooort for spatial planning and eco-environment nrotection in New Hefei.

Post-occupancy Evaluation with Emphasis on Thermal Comfort： A Case Study in Public Squares

The article presents a case study about thermal comfort in two public squares located in the coastal region of southeastern Brazil, within a post-occupational assessment context where it was sought to estimate the thermal sensation and perception of the users generating systematized knowledge about the built environment. The objective is to instruct future interventions for improvement in the living condition where it is particularly important for the success of the activities predicted there. Surveys on thermal comfort along with goers of the squares were held on three consecutive days in April 2013 and February 2014 with microclimate monitoring of the places adopting the predictive PET （physiological equivalent temperature） index calculated based on the bioclimatic model Rayman. The obtained data set generated valuable information about the pattern of thermal comfort allowing understanding the analytical correlations between PET index, climate variables and the perception of comfort. The article seeks to contribute towards the recognition of bioclimatic specificities in the project process aimed to the improvement of the environmental and social performance of public squares and aspects that are relevant to the urban planners.

Evaluation on Pipao＇ s Construction Comfort by Fuzzy Theory

Comfort is one of the most important attributes demanded by bra consumers. It reflects the psychological feeling of a wearer.Different kinds of knitted fabric are chosen as bra samples in this paper. This subject studied the bra＇s comfort sensations by carrying out a series of subjective wear at temperature at 21± 2℃ and humidity of 65±3%. By exploratory analysis of the subjective ratings on 3 mainly sensory factors （thermal, moisture and tightness）, the relationships between 3 factors are studied under three conditions, before, during and after movement. This study is focused on subjective evaluation ofbra＇ s comfort sensations of made of different knitted fabrics. Finally, based on fuzzy theory, the comprehensive comfort sensations of these fabrics in different wear conditions are analyzed and evaluated.

Suitability Evaluation for the Construction of Decentralized Wastewater Reclamation Facilities in Beijing

水资源的缺乏使越来越多的城市和城区开始使用中水作为额外的经济合理的供水水源,并为此制定相应政策。然而,不适宜的中水利用政策往往对用水户使用再生水产生不利影响。本研究目的在于评价中水设施建设适宜性并分析不同行业的中水利用适宜情况,为制定或修订中水利用政策提供参考。本研究以北京市为研究区,在中水生产成本影响因素分析基础上,得到了中水设施建设限制因素和中水设施建设适宜条件,并对北京市机关、高校、饭店的用水户进行了适宜性评价。本研究结果表明,运行水量对中水生产成本有决定性影响。有效原水量对应的给水量、有效中水需求量、建筑面积适合作为中水设施建设影响因素,它们的下限可作为中水设施建设适宜条件。本研究通过分析北京市部分机关、高校、饭店用水户的用水情况,得到这些行业的中水设施建设适宜条件,并用于适宜性评价。评价结果表明,大部分机关用水户和大部分一、二星级饭店不适宜建设中水设施,而大部分高校和大部分三星级以上饭店适宜建设中水设施。
