A river health assessment index system was established, focusing on the realistic needs of county sustainable development and the refined management of small- and medium-sized watersheds. The index system takes into consideration the United Nations’ Sustainable Development Goals (SDGs) and the vulnerability characteristics of small- and medium-sized watershed ecosystems and consists of 15 indicators in four areas: clean water, sanitation, the present status of biodiversity and threats to biodiversity. This paper uses the minimum discrimination information principle to construct a dynamic combination-weighting technology composed of a subjective weighting method (document frequency method) and an objective weighting method (entropy weight method). Using the fuzzy matter-element analysis theory, a comprehensive river health assessment technology system was constructed. Baoxing County was chosen as the research area and the results reveal that: (1) Key indicators are the biodiversity index of fish, water use intensity, endemic or indicative species retention, and chemical oxygen demand (COD) emissions. (2) The Euclid approach degree of Baoxing County indicates that the entire river is in a moderate state of health. In the future, towns must take targeted measures to coordinate the relationship between the ecological environment and socio-economic development, and enhancement and releasing must be prioritised.

Under field research in Shaanxi province, the rural infrastructure project evaluation index system based on sustainable development is proposed to promote the sustainability of the project during decision and regulate the construction of rural infrastructure. Corresponding to the structure entropy weight method defining the index weight, the system consists of 9 evaluation factors and 46 evaluation indexes from economic, social, environmental and technical is built up, and taking Shannan district and Guanzhong district in Shaanxi province as examples to do empirical analysis. The result exhibits the local development rational, which proves the validity of rural infrastructure project evaluation index system based on sustainable development.

Tourism destination is a special area typical of the man-land relationship interaction. Eco-efficiency evaluation of tourism destination is a basis for developing inclusive and sustainable development policies and measures for tourism destination. This paper discusses the progress on tourism eco-efficiency from three angles-concept definition, measure methods and empirical study. Three aspects of deficiency were shown in the present study. One is the research perspective. Most researches on tourism eco-efficiency are from the level that human material production behaviors influence environment, however researches from the level that human consumption behaviors influence environment are inadequate. The other is the research content. The researches mainly focus on the value and impact two aspects, while the measure concerning value and impact is incomplete. The last part is research method. Though, currently some scholars have already applied ecological footprint analysis method, material flow analysis, ecosystem health assessment to the evaluation of regional eco-efficiency research. The methods about the measure of eco-efficiency which include priority structure method, multi-objective programming method, ecological topological method, data envelopment analysis, ecological cost value index are suffering highly controversial, owing to having inherent defects on characterizing natural resource consumption, environmental pollution, ecological service value, non-polluting ecological impacts, human development and so on. Consequently, from the view of input, output and process of logistics, energy flow, currency flow of tourism destinations natural-economic-social-tourism complex system, making eco-efficiency as an entry point, aiming at achieving sustainable development of tourism destination, studying on tourism eco-efficiency, it will be the frontier research area of Tourism Geography.

Grassland resources are an important part of land resources. Moreover, it has the functions of regulating the climate, windproof and sand fixation, conserving water sources, maintaining water and soil, raising livestock, providing food, purifying the air, and beautifying the environment in terrestrial ecosystems. Grassland resource evaluation is of great significance to the sustainable development of grassland resources. Therefore, this paper improves the BP neural network, uses the comprehensive index method to calculate the weights in the analytic hierarchy process, and constructs a water resources carrying capacity research and analysis system based on the entropy weight extension decision theory. Meanwhile, this paper analyzes different levels of resource and environmental carrying capacity to achieve the purpose of comprehensive evaluation of resource and environmental carrying capacity. In addition, based on the theory of sustainable development, under the guidance of the principle of index system construction, this paper studies the actual situation of grassland resources and the availability and operability of data, and combines with the opinions given by experts to form an evaluation index system of grassland resources and environmental carrying capacity. Finally, through the actual case study analysis, it is concluded that the model constructed in this paper has a certain effect.

AbstractThe implementation of circular economy in wood industries is an effective way for future sustainable development. The wood industries in China are not in the direction of circular economy approach due to less availability of assessment/calculation data of pollutants as per life cycle assessment (LCA) criteria. The present study focuses on the calculation of emission and pollutants from wood industries as per LCA; the emission and pollution data were collected from fiberboard Medium-density fiberboard (MDF), plywood and particleboard (PB) production. The comparative analysis of dust emissions, industrial waste gases and chemical oxygen demand (COD) were performed among three wood industries. The results revealed that the fiberboard industry was the highest emitter of dust, industrial waste gas and COD; and particleboard industry was the least emitter. Further, results indicated that pollutant index of wood industries were significantly changed between 2015 and 2017; the industrial waste water discharge increased five folds and the COD, dust and industrial gases increased two times. This study provides with the emission and pollutants data of wood industries as per LCA to promote the sustainable development for circular and low carbon economics.

Rapid industrial development has caused a series of environmental problems, which is not conducive to sustainable development of society as a whole. It is necessary to build a sustainable development evaluation system. Most of the existing literature has evaluated corporate sustainable performance from the economy, environment and society on the basis of triple bottom lines. Considering the research gap and the practice need, an evaluation system is established from four dimensions, referred to as economy, society, environment and responsibility management, and 29 indicators are designed to measure these four dimensions. Twenty seven listed Chinese mining corporations are selected as research samples, and the entropy-weight-based Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method is applied to calculate indicators’ weights. Results show that the four dimensions of sustainable performance weights from high to low are society, environment, economy, and management process.
