Causation analysis of environmental issues, their present status and development trend of environmental science in China

This paper discusses the causation of environmental issues, their mechanism of forming process. It is well known that the human induced global and regional environmental pollution and ecological damage and their negative impacts on environments for human survival are new phenomenon occurred on the planet where we live, and they are also new features of modern earth surface. Environmental pollution and ecological damage are identical in source of origin, but they differ from each other in nature,hence, solutions to each of them also vary. Environmental pollution and ecological damage are two types of environmental issues that interact each other. It is an universal phenomena of global extent occurred upon ertering into humanistic (amthropoloqical) periodic product on earth. The formation mechanism is considered as new concept: four chains of source, flew, field, effect accountable for environmental issues can thus be identified. The last part introduces the present status of environmental pollution and eccological damage, and discusses development trend of environmental science in China.
