A Study On The Optimized Goal Mode Selection And Measures Of Jiangsu Coastal Shelter Forest

Based on jiangsu coastal shelter forest construction situation, learning from predecessors’studying results, the coastal protection forest model has been a systematic research on theoptimization problem. With different structure of the coastal shelter forest mode as thebreakthrough point, based on the perspective of input and output design evaluation indexsystem. Using the index system, the different structure of the coastal shelter forest mode inputand output measurement of specific indicators, through the methods of dynamic evaluation,comparison and analysis it is concluded that the optimal coastal shelter forest model, it putsforward the model of jiangsu coastal shelter forest optimization measures and Suggestions, anddraw the following conclusion:(1)From the perspective of the tree structure of the selected in the jiangsu coastal shelterforest construction of three important afforested pattern. Poplar pure forest model, Acacia,poplar, ginkgo and other mixed mode and pear, persimmon and other pure or mixed mode.(2)Based on the perspective of input and output, designs the evaluation index system ofjiangsu coastal shelter forest model. Using the index system, calculation of jiangsu provincethree coastal shelter forest model, the cost of investment and economic output. Poplar pureforest model annual cost1910.99yuan/hm2per unit area,53647.27yuan/hm2benefit output;Acacia, poplar, such as ginkgo mixed mode each year cost3949.2yuan/hm2per unit area,47188.51yuan/hm2benefit output; Pear, persimmon and other pure or mixed mode each yearcost2905.74yuan/hm2per unit area,38583.78yuan/hm2.(3)To calculate the three coastal shelter forest and input and output per unit area than thepresent value of the index. Poplar pure forest model present value index is9.771, input andoutput per unit area than for1.07; Acacia, poplar, ginkgo mixed mode such as present valueindex is4.158, ratio of input and output per unit area1:11.95; Pear, persimmon and other pureforest or mixed present value index is4.619, ratio of input and output per unit area1:13.27.(4)Evaluation from the perspective of economics analysis of three kinds of coastal shelterforest model, Poplar pure forest model because of its higher present value index, Lininput-output ratio is high, is considered to be more optimal mode in three modes.(5)Target pattern of jiangsu coastal shelter forest optimization measures and Suggestions:strengthen the coastal shelter forest related research, actively explore effective mode of thecoastal shelter forest, strengthen the support of the coastal shelter forest investment, securitytechnology support, perfect the service system of science and technology, build strictsupervision and management mechanism.
