Based on the structural characteristics of the wetland ecological environment, we analyzed and evaluated the ecological functions of Linghe estuarine wetland quantitatively with methods of AHP and index judgment. The results showed, functions of regulating floods, biological products and soil conservation played relatively important role. The complex function of Ling estuarine wetland is in common level; the ecosystem is relatively stable to play fundamental ecological functions. AHP method made the ecological function indicators that are difficult to quantify more simple and intuitive. The article developed a new way of planning, management and conservation of the wetland with AHP method in sustainable development of Linghe Estuarine wetland.

Pajajaran street is one of the main street in Bogor city which has been famous with a high density of vehicle so it has a of high levels of air pollution potential because of the vehicle emissions. This study was conducted to analysis the effectiveness of plants to absorb pollutants in the road side trees based on an assessment of the physical characteristics of the trees to support the surrounding environment and provide recommendations for increase the ecological function of Pajajaran Bogor road side trees in reducing the air pollution. The method of this study used descriptive analysis, spatial analysis, and air quality analysis used the CITYgreen 5.4. The ecological function evaluation of Pajajaran Bogor road side trees in reducing the air pollution shows there are 958 trees which very appropriate to absorb the air pollution, 238 trees which appropriate to absorb the air pollution, 70 trees which less appropriate to absorb the air pollution, and there is no tree which not appropriate to absorb the air pollution. While the function of absorbing particles evaluation shows there is one tree which very appropriate in absorbing the particles, 1136 trees which appropriate in absorbing the particles, 101 trees which less appropriate in absorbing the particles, and 73 trees which not appropriate in absorbing the particles. The result of analysis used CITYgreen 5.4 shows Pajajaran Street Bogor can reduce pollutants in the amount of 2544 lbs (1,298 ton/year) with economic benefits value by $ 6.268 (Rp75.167.175,12). Pajajaran Street Bogor need to add as many as 485 trees in an area that does not have a tree planting so as to optimally reduce the amount of pollution as much as 1.66 ton/year, equivalent to the economic value of Rp 121 095 216.

Quantitative assessment can scientifically determine the health status of a regional ecosystem, identify regional eco-environmental problems, and assist in promoting regional sustainable development and environmental management. Taking China’s important ecological function region, the Yellow River affected area as an example, this study constructed an extended evaluation index system based on the pressure-state-response framework, and remote sensing and GIS techniques were used to dynamically evaluate the spatial and temporal characteristics of ecosystem health in the study area. Furthermore, influencing factors on ecosystem health in the study area were extensively analyzed using the GeoDetector model. The results show that the ecosystem health level in the study area shows significant spatial heterogeneity from 1995–2015, and showed a fluctuating change process. Areas with large fluctuations in health level were mainly distributed in extreme climate areas, ecologically fragile areas, on plains and in hilly areas. Spatial differences of ecosystem health were well explained by using the biological abundance index, relief degree of land surface, soil type, annual average precipitation, elevation, annual average temperature, and population density. Influencing factors have significant interactive effects on ecosystem health.

This paper focused on how to apply Value Engineering to optimize the low carbon scheme of construction, studied how to construct evaluation index system of low carbon solutions, and proposed the method of determining the function importance coefficient according to consumer demand and determining the real cost of low carbon construction. Through analyzing the matching degree between function and cost according to function evaluation value and real cost of function, the method of determining the low carbon optimization scheme was proposed.

The chemical industry is the focus of circular economy construction, and the construction of evaluation index system of circular economy is an important work. In this paper, a circular economy evaluation index system that may be used for quantized evaluation for the chemical industry is established based on the previous research results, where the weight value of the index system is obtained by the AHP method. The rationality of the evaluation index system is verified through the case studies.

Usability is the basic properties of the product, and it is the overall evaluation to the product usability. In this paper, firstly, establish a usability evaluation index system of the welding clamp. Then, use the improved fuzzy synthetic evaluation method to assess the usability of welding clamp. In an improved fuzzy synthetic evaluation model, the index weight which is identified by using AHP method is amended objectively by using entropy technology, the resolution ratio is improved by classifying the differences between qualitative indexes and quantitative indexes. Finally, get the evaluation results of the usability of a welding clamp according to the method above.
