The aim of the present study was to obtain the water of reuse from domestic sewage provided by Anhumas Sewage Treatment Station, from Campinas, Brazil. The construction building waste was used in decantation of sludge from sewage. The sewage water was filtered in a membrane of microfiltration and used in irrigation. Bean seeds are used in germination on degraded soils. Ecological cost was measured...
Agriculture is the foundation of national economic development. Agricultural sustainable development is an important part of the social-economic sustainable development and a key historical task of building new socialist countryside in our country. Xinglong town is a typical representation of black cultivated land in Heilongjiang Province. This study presents an ecological analysis of the agro ecosystems...
Land resources are the foundation of existence and development of human being, its an important part of country resources. Urbanization and industrialization is very fast in Dalian City.In the process, too much agricultural land was transformed into construction land,which aggravated the contradiction between people and land.So how to achieve sustainable development and use of land resource, keep...
This paper preliminarily discusses land potential in regional land use based on the relative factors. In terms of system, predominance in a regional land quality, land circumstance and geographical location is called regional land potential. Among these factors, the geographical location is decisive factor to land potential. Land potential will follow the law of conservation of energy, that is, the...
The Pressure-State-Response model (PSR) proposed by the OECD and UNEP in 1994 was used to evaluate ecosystem health, In this paper, the PSR concept model was cited to reflect the pressures upon land resource in different time exerted by human activities, the responses of society to these pressures, and the state changes of land resources in different phase. A workable indicators system of PSR model...
An integrated, semi-automated system is presented for the rapid and efficient testing and production of research-scale quantities of biochar. This biochar, produced from agricultural waste materials, can easily be incorporated in future sustainable livestock farming systems. These farming systems will be able to diversify farm income by generating a consistent, predictable, marketable product. Before...
The subsided land of mining area is not only the land and ecological environment damage caused by the exploit of mineral resources but the very important land resource to sustainable development of the resource-based cities. A view is put forward that the ecological reconstruction of collapsed land of the resource-based cities should be planed based on its zones. Taken the Pingdingshan City as a case,...
With the theory of sustainable development as guide for the agriculture of China, farmland in Houhu region of the Jianghan Plain in China was selected for case-study on introduction of the niche-fitness theory into multi-suitability evaluation of tillage. Quantitative analysis of niche-fitness and restrictive factors for rice, wheat, cotton and rape, were carried out by means of calculating niche-fitness...
In response to Vice President Cheney's famous dismissal of conservation as a mere "sign of personal virtue," I argue that personal virtue may be a necessary even if not a sufficient condition for "a sound, comprehensive energy policy." The most effective and worthwhile approach to energy policy is one that seeks both to change the overall system of energy production and distribution...
Cellular automata and the DSSAT crop model are used to regionalize site specific information of winter wheat and maize in the North China Plain (NCP). On the basis of the spatial explicit IRTG (1st Sino-German International Research Training Group) geographic database AEIS (Agro-Environmental Information System) on climate, soils, crops, agricultural management and sociological data these two different...
Significant attention was paid in all developed countries to the agriculture until the seventies of the last century. It was due to the food deficiency in the post-war period. The period of the intensive agriculture production in the former Czechoslovakia lasted longer, due to the necessity of the high self-sufficiency in food feed and raw materials, produced in the agriculture in the closed system...
