Study on site selection of Daiyun Mountain Reserve based on ecological value
摘要
Abstract
How to effectively protect biodiversity and maintain ecological safety by using the minimal sites in planning and designing the nature reserve is a urgent problem needed to be solved to relieve the contradiction of ecological protection and economic development. This work was aimed to discuss the applicability of the site selection algorithm. Based on the ecological assessment of Daiyun mountain district, combining the spatial feature and the requirements of the ecological status, a space optimization proposal of Daiyun mountain nature reserve was put forward. Combining the vegetation diversity characteristics of reserve and the application of site selection algorithm, the area of Daiyun Mountain containing 18 762 sub-compartments was segmented into grids. According to the result of resource survey, the ecological values for each grid were calculated and the ecological value distribution plot was drawn considering the characteristics of the land, the varieties of trees, the canopy density of forest stand, the average height of trees, the mean diameter of trees, the age composition of trees and the site quality. The improved Önal-Briers optimization model was adopted to optimize the selection of the area of the nature reserve. According to this method, we selected 5 candidate regions to compose the nature reserve of Daiyun Mountain including 88 sites ( grids) . Among which, 2 candidate regions ( No.2 and No.3) are belonged to the original nature reserve area and the new added ones are located at the east ( No.4) , north ( No.1) and southeast ( No.5) of the original nature reserve area, respectively. Moreover, considering the criteria of nature reserve the regions of No.2, No.3 and No.4 are concentrated and the reserve area formed by these three regions can efficiently weaken the influence of edge effect. So the regions, No.2, No.3 and No.4, are the optimal combination for constructing the Daiyun Mountain National Nature Reserve. The optimal design of Daiyun Mountain nature reserve covers two candidate regions and one east candidate region of the original nature reserve which realizes the optimal combination between the number of sites and the ecological value and protect the overall vegetation diversity to the utmost. The site selection algorithm may have applicability in the design research of nature reserves of forest ecosystem types in domestic and supply a new idea to the design research of nature reserves of forest ecosystem types.关键词
