This paper analyzed the existing conditions and tendency in forest ecological restoration of the province and revealed the confronting problems in ecology and economy. The authors divided Jilin Province into three ecological economic zones, including nid-west farming and stockbreeding area, east hilly diversified-operation area, and Changbai Mountain national forest area, and discussed the direction and tasks of forest ecological restoration of each zone. Some Countermeasures and suggestions were put forward for restoration of forest ecology of the province.展开更多

Application of fertilizers and pesticides in large quantities greatly aggravate environmental pollution of this area, and water pollution has worsened to an unbearable condition. Two sampling farms (respectively 1 hm2) under rape-rice rotation and wheat-rice rotation were selected as studied ecosystem and a 5-yr-old Poplar forest and 8-yr-old Metasequoia forest were chosen in the selected areas. By collecting samples of Nitrogen, Phosphorus in water, crops and underground of forest, the transfer and loss of N and P (main water pollutants) in faming ecosystem were studied, and the effects of forest belts on non-point source pollution of agricultural lands was analyzed. The results indicated that the transfer and loss of N and P vary with means of rotation, types of crops and the amount of fertilizer application. Buffering forest belts betweens farmlands and ditches can effectively stop and purify such elements as N and P in soil runoffs, thus controlling non-point source pollution of agricultural lands. When the width ratio of farmland to forest belt is 100 to 40, 50.05% losing N, 29.37% losing P can be absorbed by forest under rape-rice rotation and 30.98% N, 86.73% P can be absorbed by forest under wheat-rice rotation. When the width ratio of farmland to forest belt is 150 to 40, 33.37% losing N, 19.58% losing P can be absorbed by the forest under rape-rice rotation, and under wheat-rice rotation 20.65% lost N and 57.82% lost P can be absorbed. There is only some purification effect when the width ration of farmland to forest belt is 200 to 40. Based on model of buffering forest belts, the width ratio of farmland to forest is determined between 100 to 40 and 150 to 40, because it not only can purify water, but also occupy less farmland. It is suggested that Poplars, with the characteristics of fast-growing and high value, are suitable to be planted as shelter-forest in Taihu Lake Watershed.展开更多

The Natural Forest Protection Project of this area has an important bearing on the social and economic sustainable development of Jilin Province or even the whole forest area in NE China. This paper summarized general conditions of natural forest in Changbai Mountain state-owned forest area and put forward six problems need to be urgently solved and five strategic suggestions on natural forest protection and sustainable management.展开更多

China, as a state member of WTO, is challenged by the WTO's agreements and the principles to guideline China sustainable forest development in the future. Forest resources in China will be protected as the basic sections of natural resources. The administrative function of Chinese government will be reformed by the condition of WTO's principles. So, the aim of China forest sustainable development is prior to deal with the relationship between the environment protection and development of economy. Under the condition of the WTO's principles and as a base on the international customary laws, the issues of China forest sustainable development focus on the China forest system reformation that applies for the China nature forest stratagem by the laws and protects the China environment for the sustainable development under the condition of science development, especially in the China forest protection and in dealing with the relationship among the environment and the economy development and others. Establishing the zoological forest industry is basic requirement by both the WTO's agreements and the WTO's principles, especially under the GATT 1947 Art XX, and other principles to protect the China forest sustainable development and to create the international environment for China forest.

This is accomplished by reviewing the impact that the introduction of automation technology has made through the longwall shearer automation research program of Longwall Automation Steering Committee(LASC). This result has been achieved through close integration of sensing, processing, and control technologies into the longwall mining process. Key to the success of the automation solution has been the development of new sensing methods to accurately measure the location of longwall equipment and the spatial configuration of coal seam geology. The relevance of system interoperability and open communications standards for facilitating effective automation is also discussed. Importantly, the insights gained through the longwall automation development process are now leading to new technology transfer activity to benefit other underground mining processes.展开更多

In China, great progress has been achieved since 1956 when the first nature reserve was established. However, conflicts between nature reserve officials and community members, and differences be-tween conservation and utilization of natural resources suggest that the traditional community affair model is unfit to some de-gree. A more workable and economically sustainable model is recommended. Co-management appears to be the preferred management model. International conservation organizations have carried out projects in Chinese nature reserves in recent years, and co-management is thought to be an effective approach to resolve conflicts coming from community and to improve nature reserves management.展开更多

However, most residents are ordinary people. Therefore, it is necessary to change the awareness of sustainable living environments, not only on the construction side but also the residents. In recent years, the number of cases of residents＇ participation in planning, maintaining, and repairing increased. However, sometimes youths and children, who might spend a lifetime longer than adults in a city after the developments have been done, are not included in this ＂Residents＂. Conceming youth and children＇s participation, CFC （child friendly city） is one of the good practices for sustainable development. It was launched by UNICEF （United Nations Intemational Children＇s Emergency Fund） and UN-Habitat in the Habitat II in 1996. City governments, especially in European countries, started to view CFC as their key concept for preservation and/or sustainable development. CFC means not only being ＂Children＂ friendly but also ＂All people＂ friendly. Various effects have been reported since the Historic Cities/districts included CFC in their city planning as a common concept, especially in education, community re-development, and operation and maintenance by the community. It is expected that better city planning in preservation and sustainable development can be achieved by adding CFC concept. In this research, an ideal way of city planning involving resident participation and the possibility in the future are analyzed based on case studies. Then a strategy of sustainable development and community planning involving youth and children＇s participation is proposed.展开更多

To further the sustainable development evaluation system of coal mining cities in Heilongjiang province, based on the analytic hierarchy process （AHP） method combined with operational and scientific principles using Saaty＇s 1-9 scale method to construct the judgment matrix from five aspects, such as economic development and environmental quality, this paper establishes the comprehensive evaluation index sys- tem of sustainable development of coal mining cities in Heilongjiang province, including comprehensive index of industrial economic benefits and the contribution rate of science and technology. In addition, using fuzzy comprehensive evaluation method, a comprehensive evaluation is made on the indices of the four major coal mining cities of Heilongjiang. The result shows that the coal mining cities are not bet- ter than Datong of Shanxi province in many indices. The economic development and environment quality are the most important indices of the targeted layer influencing the sustainable development of coal min- ing cities of HeilonKiiang, and their index weights are 0.4358 and 0.2844, respectively. These two indices including comprehensive index of industrial economic benefit and the ratio of environmental protection investment to GDP are the key elements influencing the two aspects.展开更多
