On the ecosystem health, definitions from utilization and ecosystem views are introduced, the contents and difficulties in assessing it are discussed. On the biodiversity enhancement, the relationship between forest structural complexity and forest biodiversity are discussed, the significance of old growth structure are highlighted, and measures of changing forest structure to promote forest biodiversity are put forward. On the landscape planning in forest management, some patterns, theoretical foundations and models are introduced, especially three conceptual models, i.e., key habitat\|corridors model, nature landscape model, and supportive features model. On the alternative silvicultural systems, reasons for developing alternative silvicultural system by mimic of nature disturbance are discussed, and some advanced techniques and their ecological basis are noted. Finally, on the ecosystem service, its contents and importance of assessment are illustrated.

Thethesis compares the characters of ecosystem service in different district, main drainage basinand different segment in it, confirms the rules that the ecosystem service value is higher insouthern area than northern area and different characters along river and ridge. The ecosystemservice value is decreased regularly with the increasing of population density and elevationby compared analysis. The results of the ecosystem service values in 1981 and 2001 shows arule that ecosystem service value is steady for whole researched region and fluctuate in localarea in LRGR.
