Ecology Risk Assessment And Management Of Forest Landscape Areas

The regional ecology risk assessment is conducted on the regional scope.its most main characteristic is uncertainty and complexity. This thesis analyzed the forest resources characteristics the ecology present situation,the disturbance and the influence of human to ecological environment of snow township forest park through the ecology risk assessment theory, The main purpose is to analyze and evaluate the press of society to snow township ecological environment influence and the harm.Followings are mainly covered:Elaborated the ecology risk assessment concept, the characteristic, the method and the flow, through reference other literatures and the theories has constructed the forest ecology risk assessment target system.Regional ecology risk assessment process:The selection end pointâ†'disturbance source qualitative and the quantitative descriptionâ†'determination and the description possibly receives the region environmentâ†'utilization appropriate environment model which affects to estimate exposure of the space and time distributionâ†'quota determined in the region environment between exposed and the biological response reciprocity, obtained the final risk assessment result.This research conducted a whole risk assessment to the snow township through the remote sensing pictures, presented data and investigation. The local main ecology risk is from the social press that humanity's activity.The risk value: the maximum value 2.53, the minimum is 1.02, the mean value is 2.070, the high risk area occupies the overall region 64.0%, the moderate risk accounts for 11.51%, the light risk plot accounts for total area 17.46%, the region ecology risk composite index is 1.991, integrated risk is close to severe risk.This thesis finally suggested that: firstly, protect the primary forest; Secondly, to conduct the ecology restoration; thirdly, positively explores the ecology compensate system.
