Moreover, the tilth soil is uniform in size and in small, broken bits and loose. It expands the new soil ＂four warehouses＂ （namely soil nutrient warehouse, water warehouse, oxygen warehouse and microbial warehouse）, and under the conditions of ＂three no increase＂ in chemical fertilizer and pesticide, irrigation water and labor input, various crops show a increase of 10%-30% in yield （average increase by 25.48% in the 23 rice, wheat and corn planting areas of several provinces）, 5% in quality, and 1 time in water retention. And the sustainable production-increasing ef- fect lasts 2-3 years after once Fenlong tillage, with the comparative efficiency reaching about 20%. It is suggested using Fenlong to activate the arable land, saline land grassland and rivers resources, so as to drive the construction of green agriculture ＂3＋1＂ industrial system, which can promote the realization of the increases in available agricultural resource stock, quality food resource stock and available water resource stock in China and even in the world, realize the ＂two responses＂ to ecological environment deterioration and climate warming, and achieve the harmonious coexistence of human beings and nature.展开更多

According to the research CO2 is the main component of greenhouse gases and the main culprit of causing the greenhouse effect. The ocean is a huge repository of carbon, water can dissolve a large amount of CO2, in the ocean, a large number of plants and planktonic algae absorb CO2 to produce 02, It is a very large gathering place （sink）. At the same time, CO2 aggregation in the ocean seawater acidity increases, impact on fishery resources, sources and sinks of CO2 were discussed in the paper.展开更多

Firstly, this paper analyzes their connotation and relationship, which could be simply described that in virtue of element integrating and structure optimizing, agricultural system may achieve multifunctionality to meet increasingly diverse demands. As a case study of Suzhou, it concludes that Suzhou has a LP-dependence on agricultural element, and the growth extent of agricultural productivity correlates to the ratio of agricultural labor reduc- ing rate to farmland reducing rate. Agricultural structure of Suzhou changed with time, and in the early 1980s and 2000s it was most notable. Correspondingly, agricultural function has experienced a succession process: 'production', 'production-living', and 'production-living-ecology'. At last, based on questionnaires and interviews, some new characteristics and problems of agricultural development in coastal developed region of China have been put forward. Meanwhile, some typical patterns of modern agriculture in Suzhou which adapt to system evolving are also brought up such as export-oriented agriculture, enterprises-leading agriculture, agricultural science and technology parks, characteristic and stereoscopic agriculture, tourism and sightseeing agriculture.展开更多

At last, it can be identified that ecological footprint is a good method to measure resourceutilization and environmental pollution in various subsystems of an integrated ecological industry.展开更多

Learning from changing tendency, industrial structure convergence in the five provinces and municipality in the Bohai Economic Rim tend to be increasingly intense. For integration of industry cooperation development in Bohai Economic Rim, it is faced with massive separation, industrial development convergence and is restricted by institutional and ideological barriers. As strategic choice based on interest tending, integration of industry cooperation development in Bohai Economic Rim should be further integrated on development concept of industrial transformation to promote institutional system of the integration of industrial development and optimize the industrial layout and division system of Bohai economic rim.展开更多

This paper firstly conducts the comparative analysis between traditional and ecological industry as well as traditional and modem industrial engineering, and in- dicates that eco-industrial engineering is an inevitable choice for sustainable development of modem industrial engineering; Then, based on industrial ecology, environmental economics and sustain- able development theory, the connotation and definition of eco- industrial engineering are proposed, and the theoretical and practi- cal development of the concepts of eco-industrial engineering are further investigated. Furthermore, the research subject, research content, academic system architecture and evaluation methods of eco-industrial engineering are discussed. Finally, combining the current scientific and technological development, we put forward the important scientific value and practical significance of con- structing eco-industrial engineering for the utilization of these concepts.展开更多

Differ from ecologists and environmentalists who regard industrial ecosystem as the natural ecosystems in which material, energy and information circulates, this paper defines industrial ecosystem as a set of factors that are vital to the development of a certain industry and their interrelationship. The industrial ecosystem consists of three sub-systems that are innovation ecosystem, production ecosystem, and application ecosystem, and subsidiary factors that include factor supply, infrastructure, socio-cultural environment, international environment and policy system. The industrial ecosystem is characterized by interdependencies, complex interactions, self-recovery and co-evolution. The development of an industry is＇ the result of the reaction of the whole industrial ecosystem; therefore, the competition in strategic emerging industries among countries is in essence the competition in industrial ecosystems. Those countries which are able to take the lead in setting up complete industrial ecosystem will occupy advantage in developing strategic emerging industries. Cultivating and developing strategic emerging industries requires promoting the development and coordination of the whole ecosystem.展开更多
