Study On Conflict Measure And Optimization Of Coastal Zone Based On The Ecological-production-living Spaces

The coastal zone is transition belt contacted inland and ocean,with appropriate climate condition and rich natural resources.Furthermore,it is the bridgehead of economic development since the reform and opening in China,is the core zone of the construction of modern economic system,and has significant advantages among agglomerating the population industry,promoting the core competitive ability,and building livable and appropriately industrial environment.In a word,it occupies vital important strategic position in the process of social development.However,with the quickening urbanization in the coastal area and the constant increased population pressure,there have emerged a series of conflicts between resources and environment,such as the decrease of cultivated land and forest vegetation,the degradation of grassland,the intensified soil erosion,the degradation and salinization of soil,the deprivation of fresh water resources,etc.,to a great extent,which have caused the increase risk of the regional ecological environmental.The 18th National Congress of the Communist Party of China have figured that facilitated constructing intensive and efficient production space,moderately livable living space and picturesque scenery ecological space.How to coordinately deal with the land use among ecological space,living space,and production space in the coastal area has become one of hot topics of land study in our country at present.This paper,from the perspective of ecological-production-living spaces,explores the theoretical methods of the suitability evaluation of utilization,the conflict measurement of Utilization status and plan and the optimizing Utilization about the "three spaces" in coastal zone,and carries on the empirical analysis with a case study of Zhuanghe coastal zone.The paper made the following conclusions primarily through the research:(1)Theoretical methods of the suitability evaluation of utilization has formed initially in the ecological-production-living spaces of coastal zone.This paper,from the three evaluation target--production space,living space and ecological space,constructs the 8 criteria and the 18 underlying index evaluation system:Specifically,production space tends to these indices:input intensity,usage degree,output effect etc..Living space builds the index system from the living condition,the convenience of tirps,and cheap servvice etc..While ecological space takes the ecological quality and space structure etc.into account.Index weight mainly adopts the methods combined entropy weighting method and expert estimation,with comprehensive weighted model and the obstacle degree model as the evaluation method.(2)This article mainly measure conflict from two aspects using the status and using planning of coastal zone.The article establishes,through conflict index of landscape ecology,the coastal zone's conflict model of using status:space conflict = external pressure + space exposure + space risk effect value,its formula labels as:SC=P+E+S(SC for space conflict level;P,E,S,respectively,for external pressure,space exposure and space risk effect value).According to the comprehensive measure of spacing Violations,the utilization degree of conflict has been divided into four types:"serious out of control","basic out of control","base control" and "stably control".Utilization planning conflict measure method of coastal zone,after exploring and integrating land planning,urban and rural planning,forestry planning and Marine planning,is using spatial analysis platform of ArcGIS,geographic information systems,to conduct the overlay analysis of these four planning,namely,conflict degree of measurable planning.Its types majorly are conflicts of two plans,three plans and four plans.This method of measure the conflict provides a useful technical method and reference for the national coastal zone.(3)This article mainly regard technology method of multiple planning integration tas the breakthrough point,promoting the utilization optimization of ecological-production-living spaces of coastal zone.The paper,on the basis of finding out the conflict degree between utilization status and utilization plan of the "three spaces" in coastal zone,combined the results of suitability evaluation,puts forward the technology method of graph spot determination of these land use planning,forestry,urban and rural and Marine planning etc..The general principle of basic farmland protection,of land planning,and construction limited area,of forest land planning,precede other areas in the four department special planning.Important ecological use area is prior to construction land of the four special planning area.Meanwhile the land for critical infrastructure or livelihood projects prefers to other construction of the four special planning area.The methods provide technical support for reaching the coordinate,sustainable utilization in coastal zone.(4)The results of the conflict measurement of Utilization status and plan in Zhuanghe coastal zone's ecological-production-living spaces is basically truthfulness.By the constructive landscape ecology model,in 2014,the comprehensive conflict measure value of Zhuanghe coastal zone's "three spaces" is 0.56,relatively in a high level,but basically in controllable range in general,and the stable and controllable area is lesser.From the use conflict of three type space,conflict degree of living space of Zhuanghe coastal zone is higher,in 2014,which chart spot area of serious out of control has accounted for 7.35%;The change of production space and guarantee space is relatively stable;Ecological space also is relatively good,with stably and controllably high proportion.From the point of nearly 10 years evolution,the comprehensive conflict value of space usage of Zhuanghe coastal zone has raised 6%,from 0.53 in 2004 to 0.56 in2014.The conflict intensity of space utilization stays relatively high position,whose development and change relatively stable overall,but its direction towards incontrollable state and the larger area of space use conflict is on the rise.From the type of conflict,the area of region of "stable control" and "basal control" presents downward trend,while the area of region of "basically out of control" and "seriously out of control" appears ascendant trend in the conflict of ecological-production-living spaces of Zhuanghe coastal zone.There have emerged considerable overlaps in the two plan conflict measurement through measuring the exploiting and planning conflict in Zhuanghe coastal zone's ecological-production-living spaces—the plan of land utilization and city layout hold large overlaps in Central city and Huayuankou economic zone in Zhuanghe and the land planning and forestry planning exist overlapped situation,large-scale and continuous-tablet,in the total coastal zone area;The conflicts among land planning,forestry planning and city planning are most obvious in the measurement of three plan interference,which distributed mainly in the Changsheng streets,Xinhua street,Dazheng streets and HuaYuanKou and other regions;the regions of four plan conflict--combined with Marine division—are fewer.(5)The paper has proposed the exploited optimization scheme of the ecological-production-living spaces in Zhuanghe coastal zone.Through suitability assessment of its utilization,the regions of suitable production in Zhuanghe are mainly distributed in HuaYuanKou economic zone,Xingda streets,the city streets,black island town;the livable regions distribute mostly in Dazheng town,Changsheng street,Xinhua street,Landian town;the ecological adaptable regions locate in Wu Lu town,Qingdui town,Anzishan town,Lizifang town,respectively.On the basis of suitability evaluation,The study has made the scheme of exploited optimization placement in shoreline's ecological-production-living spaces--based on the coastline result of conflict measure,according to the optimization method,namely graph spot determination technology of multiple planning conflict,it has divided the coastal zone into ten areas:the basic farmland preservation area,the aquaculture region,the industrial concentration district,the urban constructing community,the town constructing community,the mountain greenbelt,the beach wetland reserve,the port constructing area,the transportation and road land,General agriculture area,etc..And it has received a optimized layout of ecological-production-living spacesf of Zhuanghe coastal zone in 203 0,according to its corresponding relations between space classification and land use,providing a vital reference basis for the coastal zone utilization.
