Route evaluation indexes of Changsha-Jishou freeway for protecting cultural heritages and natural environment

The highway construction inevitably may cause certain influence to the cultural heritage and the natural environment along the route, particularly in design stage; if the route selection is unreasonable, it will certainly impact the natural resource seriously along the route. On the contrary, good design can reasonably develop, use, protect and promote the value of cultural heritage and natural environment. Changsha to Jishou （Chang-Ji） freeway is one section of Changsha to Chongqing freeway, which is one of the eight big west channels as planned in China; two cities of Changde and Huaihua and one autonomous region of Xianxi in western Hunan province, along which the cultural heritage and the natural resource are rich, and the natural landscape is exquisite. This paper investigates and analyzes the natural resources along the route of Chang-Ji freeway, puts forward some protection design evaluation indexes for mountain area freeway by the thought of context sensitive design. At last, the paper introduces the effect of applying the indexes to select route of Chang-Ji freeway.

Evaluation and Analysis of Provincial Differences in Resources and Environment Carrying Capacity in China

Resources and environment carrying capacity is central to not only regional sustainable development but also major function-oriented zoning. This paper presents an evaluation index system for resources and environment carrying capacity based on four aspects of carrying capacity(i.e., water resources, land resources, the environment, and ecosystems) by using a square deviation decision-making method, and on the basis of above effort evaluates the resources and environment carrying capacity across 31 provincial regions in China(not including Hong Kong, Macao and Taiwan regions of China). In addition, this paper evaluates the current state of socio-economic development, and analyzes the spatial distribution of resources and environment pressure. The results showed that distinct spatial differences in resources and environment carrying capacity and pressure across provincial regions. Resources and environment pressure is affected by both comprehensive resources and environment carrying capacity and socio-economic development. Regions subjected to lower degrees of resources and environment pressure will be restricted by resources and environmental problems through future courses of development owing to excessively low carrying capacities. By contrast, regions with higher comprehensive resources and environment carrying capacity will be subjected to excessively high levels of resources and environment pressure because of rapid socio-economic development. Both of resources and environment carrying capacity and pressure must therefore be considered in the allocation of country-binding targets to provincial regions.

Evaluation of Ecological Environment Competitiveness of Hunan Province Based on Prefecture Level Cities

Based on the data of 13 eco-environmental indicators of 14 prefecture level cities in Hunan Province from 2014 to 2018,this paper quantitatively evaluated the eco-environmental competitiveness and its advantages and disadvantages by principal component analysis(PCA).The results showed that:(1)the overall ecoenvironmental competitiveness of Hunan Province was relatively high,whereas the competitiveness level of each city and prefecture was quite different.The comprehensive score of eco-environmental competitiveness of Changsha City was 2.96,ranking the first,and Zhangjiajie city ranking the last with a score of-1.60,which indicated that there was an obvious difference in the level of eco-environmental competitiveness among different regions.(2)The overall eco-environmental competitiveness of cities and prefectures in Western Hunan Province was weak.Among the 14 prefectures and cities in Hunan Province,the comprehensive scores of eco-environmental competitiveness of 6 prefectures and cities were negative,whereas the scores of Zhangjiajie,Xiangxi and Huaihua in Western Hunan were all lower than the others.In the face of increasingly serious environmental problems,cities and prefectures should adjust measures according to local conditions and put forward specific measures to enhance environmental competitiveness.In particular,cities and prefectures in Western Hunan should give full play to their advantages in ecological resources,take the path of green development,enhance the competitiveness of ecological environment,and provide support for local economic development.

Landscape and Road Integration in Greece

This paper concerns the Strategic Environmental Assessment of the construction of some major Greek motorways： the Ionia Motorway, the Peloponnese Motorway and the Athens-Lamia Motorway. In the beginning the natural and cultural diversity of the Greek landscape as well as its conservation needs are discussed. The landscape impact assessment methodology consists of the identification of environmental goals, of sensitive landscape parameters, of environmental indicators and of acceptable impact thresholds. The selection of alternative solutions as well as of mitigation measures has been studied, on the basis of relevant environmental indicators. The developed methodology may constitute a tool for the environmental management of other road programs of great scale.

Preliminary Study on Early-warning System of Ecological Security in Water-Level-Fluctuating Zone (WLFZ) of Three Gorges Reservoir

The area,the scope as well as some ecological environment questions in Three Gorges Reservoir was briefly introduced. Then its early warning-system frame was preliminarily constructed,which includes ecological security dynamic monitoring,ecological security appraisal,ecological security forecast and ecological security decision-making management. The synthetic evaluation indicator system of the ecological security quality were initially established,which includes ecological environment pollution,land use and land cover change,geological hazard and epidemic outbreaks. At the same time,29 evaluating indicators were selected,divides into the basic factors,response factors and inducing factors,which need to be Real-time monitored.

Standards System and Evaluation Indicators System for Environmental Protection Products

Environmental protection products and equipment are important substance basis and insurance which provide supporting for to the realization of the strategic objective of reduced energy use and emissions while improving the resource economy ＆ environmental kindly society building, as well as the sustainable development economy and environment in a sustainable fashion. Here, the framework of the standards system and evaluation indicators system for environmental protection products are described based on the present deficiencies in independent innovation, lower levels of standardization, and poor operating effectiveness of such equipment in China with a goal of forcing the development of standardization, seriation and currency used in the environmental protection industry. The results presented here should serve as a reference for the promotion of quality and effectiveness in environmental protection products and equipments.
