Suitability Evaluation Of Expressway Project Land Reclamation Based On Immune Clone Algorithm

Based on in recent years Government on engineering construction project of vigorously support, and with economic development gradually high of land reclamation cost, in vigorously carried out land reclamation work while, on land reclamation cost made more strictly of limit must is future a time of development trend, so should strengthened as land reclamation work core of land reclamation suitable sex evaluation of concern degrees, in implementation land reclamation suitable sex evaluation measures inquiry of while, implementation on land reclamation efficiency and reclamation quality of research, In control while maintaining quality of reclamation reclamation costs for other engineering land reclamation suitability evaluation studies provide some references.This research to BA Guang Yu Highway Engineering land reclamation work for cases, take immune clone algorithm, to determines minimum reclamation cost and suitable to class area combination for target, building has suitable of land reclamation suitable sex evaluation model, established has land reclamation suitable sex evaluation indicators system, and to software MATLAB R2012b and SPSS as auxiliary programming calculation tool, using entropy right method determines suitable sex evaluation indicators of weight, on building model for has empirical research, on optimization results do has correlation, and Regression analysis and analysis of the effectiveness and finally draws the main conclusions are as follows:(1) Research building has land reclamation suitable sex evaluation indicators system system, will evaluation unit divided for for abandoned soil field, and construction production life with to, and construction sidewalk, and take soil field 4 a evaluation unit, select using has suitable of 13 a evaluation factor, and on participating factor be assigned value, will land reclamation suitable sex evaluation grade clear divided into height suitable, and in the degrees suitable, and barely suitable, and not suitable 4 a evaluation grade, can on research object of suitable degrees for effective to evaluation, determines has suitable of land reclamation direction.(2) Antibody groups size, and evolution times on minimum reclamation cost, and arable land has must of negative to effects, but on different of evolution times, and antibody groups size and variation probability,, optimization of results in the minimum reclamation cost changes range smaller, based on immune clone algorithm of optimization results relative compared precise sound, optimization results by parameter effects smaller, obtained results precision more high, overcome conditions constraint of limit, can in short time within obtained the model of optimal solutions.(3) By means of immune clonal algorithm for land reclamation suitability evaluation model used, in clear direction of suitability of reclamation trend for farmland and woodland in the process, appropriate class size combination of quantitative study on reclaimed, after determining reclamation suitable arable land area of 319.8509 hectares, suitable for covering 130.4370 hectares of forest land, arable land 0.0012%the overall rate, Minimum cost of land reclamation of 64.189 million Yuan, land reclamation cost optimization reduce 560,700, reclaimed before the reclamation of arable land cultivated area increased slightly to meet reclamation objectives and requirements.(4) For currently land reclamation cost rose, and land reclamation suitable sex evaluation work not involving land reclamation cost suitable sex of problem, research to more target constraint for focus, analysis reclamation of related minimum cost overhead and the suitable land area constitute Department feasible of, suitable of reclamation cost is can quantitative calculation out of, this practices widened has land reclamation suitable sex evaluation of ideas, helps land reclamation suitable sex evaluation work method research of deepening.(5) Study on evaluation index system of extension system needs to be further improved and expanded, and studied in this paper refer only to choose the ecological, socio-economic environment and land reclamation projects, the average cost of a similar class structure, temporary sites are selected only versatile 4 type, class type, only 2 species and is not related to other types of land. In light of this, future research should be based on the engineering environment and circumstances in accordance with local conditions, expanding research and engineering samples, strengthen the comparative analysis of the results of different projects and appropriate expansion of the number of temporary land type and land size, pending further study and discussion.
