Application of multi-objective programming method in forest park management regionalization
[Objective]This study,on the basis of landscape resource evaluation and multi-objective planning,is aimed to carry out the optimization of forest park functional zoning so as to provide technical support for future work.[Method]Taking Da'anding Forest Park as an example,an evaluation was conducted of the eco-resilience,visual sensitivity and landscape beauty of each landscape unit.The results were then,through linear transformation,translated into the suitability of four management countermeasures namely,key protection,maintaining the status quo,local regulation and construction and reconstruction.Finally,the multi-objective planning method(VMP)was used to investigate the optimal management countermeasures for each landscape unit.[Result](1)The evaluation index system of ecological landscape quality of forest parks was established with eco-resilience,visual sensitivity and landscape beauty as the core suggesting that the overall level of ecological resilience and visual sensitivity of Da'anding Forest Park was high,but regional differences were large.The scenic beauty was high,but the regional differences were small.(2)A linear transformation model of attribute index management countermeasure suitability was proposed to realize the transformation from multi index evaluation results to the suitability of park functional zoning.(3)The multi-objective programming method was used to seek for the optimal solution for the management of 20 landscape units in the study area,with the optimization results highly coupled with the actual landscape situation.(4)Of the five multi-objective planning methods,the ideal point method,the objective planning method and the fuzzy planning method belonged to one group whereas the efficacy function method and the maximum minimum method belonged to the other group,with the fuzzy programming method showing the best balance and thus recommended in practice and the internal planning results of the two groups are basically the same,with slight differences in between.[Conclusion]The results obtained from the research on the evaluation of the ecological landscape quality of forest parks were converted into attribute index-countermeasure suitability,the optimal solution of management countermeasures was achieved at the global and landscape unit levels by using multi-objective planning,and the results were highly coupled with the actual situation.Besides,of five common multi-objective planning methods,ideal point method,objective planning method and fuzzy planning method performed well,with the performance of the fuzzy planning method being the best.[Ch,4 fig.3 tab.28 ref.]
