A typical fiver in Yangzhou City was used to study the effects of artificial aeration, eco-brick cover, biological packing cover, and low-sited plant floating beds on the release of heavy metals from urban river sediments. This work showed that 1） the Cr release rate was decreased by 50.3%-89.6%, with an average of 59.3%, thereby reducing the Cr pollution load to the overlying water by 36.6%-82.7%, with an average of 53.3%; 2） the Zn release rate was reduced by 21.0%-88.9%, with an average of 42.3%, and the Zn pollution load of the overlying water was reduced by 38.0%-67.1%, with an average of 55.0%; 3） the Cu release rate was reduced by 27.5%-91.0%, with an average of 55.3%, and the Cu load of the overlying water was reduced by 57.1%-83.7%, with an average of 71.7%; 4） the Pb release rate was reduced by 11.8%- 79.3%, with an average of 41.2%, and the Pb pollution load of the overlying water was reduced by -1.3%-70.7%, with an average of 29.8%. We also found that the effects of in situ biological treatments on the release of heavy metals were affected by the extent of sediment disturbance. For integrated applications, high-disturbance treatments should be combined with low-disturbance treatments to reduce the explosive release of pollutants caused by sediment disturbance during the treatment operation to achieve better overall treatment effects.

Rural development is a broad and meaningful concept. It means not only economic growth butalso changes towards a better direction in economic structure , social structure , relation between human soci-ety and environment, and even political structure. Present development should not damage the environmentbut leave the same or an improved natural resource endowment as a bequest to the future. This is the devel-opment with environmental sustainability. In this paper the characteristics of rural development were reex-amined, and what environmental sustainability means and how to measure it were explicitly presented. Prac-tical approaches for achieving environmental sustainability were also given with some cases from China.

China. a country with more than 1. 2 billion people, is undergoing a rapid industrializationand urbanization. While brings wealth and hopes to people, the economic prosperity has to pay the priceof the ecological degradation. What kind of dynamics and cybernetics is needed to lead a sustainabledevelopment and ecological health? How to deal with the complicated relationships between social transi-tion , economic growth and environmental change? This article is to present some theoretical and practicalconcerns from the viewpoint of human system ecology with some cases of small towns in the coastal areaof China.

A field survey was conducted in a contaminated industrial site of southern Beijing, China to investigate the contents and distribution of the organochlorine pesticides （α-, β-, y-, δ-HCH, p,p＇-DDT, p,p＇-DDE, p,p＇-DDD and o,p＇-DDT） in the profiles of soil, and a health risk assessment was carded out with CalTOX multimedia exposure model. Results showed that mean concentrations of total hexachlorocyclohexane isomers （HCHs） and total dichlorodiphenyltrichloroethane isomers （DDXs） in soils were in the range of 13.20- 148.71 mg/kg, and 3.02-67.43 mg/kg, respectively. Organochlorine pesticides （OCPs） content peaked in the surface and declined in soil profile with depth. The amounts of HCHs in three profiles of soil were larger than DDXs. Composition analysis indicated that there was a trend of degradation of OCPs in the site, but the mean of HCHs and DDXs concentration were over the state warning standard limit （HCHs, 0.50 mg/kg; DDXs, 0.50 mg/kg）. According to current land use development, health risk assessment with CalTOX and Monte Carlo analysis showed that health risks mainly came from two exposure pathways： dermal uptake and inhalation, and the total risk values all exceeded the general acceptable health risk value （10-6）. The sensitivity analysis indicated that five parameters significantly contributed to total risk.

Ecological suitability analysis is an important step in ecological planning. It applies the basis toestablish a sound development planning. In this paper, by applying multi-dimension niche concept, an eco-logical niche suitability (ENS) model was developed. The ENS model, combined with geographical informa-tion system (GIS) and spatial simulation, was used to analyze regional resources and environmental features ,and identify the suitability of regional resource and environment to regional development. An application ofthe ENS model in Taojiang agricultural land use planning is presented.
