Evaluation Of Ecosystem Service Function Value In Shandong Yellow And Blue Economic Zone

The basic assessment of the main ecosystem on the blue economic zone of Shandong province and the the Yellow River delta efficient ecological economic zone planning value,through the 2017 statistical yearbook statistical yearbook of Shandong province and the country level city data analysis,and using reasonable methods,evaluate the value of the function value of ecosystem.The study area is divided into different ecological types,and ecosystem service function types with different points,its main function is divided into 4 categories: material production function,regulating function,entertainment function and scientific research division of the ecosystem can be finished more simple evaluation of ecosystem service function the value is more reasonable and more accurate results.The value assessment of the ecosystem service function in this study is to evaluate the service function value of the ecosystem under the standards of the human ecosystem.(1)value evaluation of forest ecosystem service functionForest ecosystem is one of the most important ecosystems on the map,this paper evaluates the forest ecosystem service function of Shandong Yellow Blue Economic Zone,and the study area of Forest Ecosystem Services Division,a total of six services were Value Evaluation respectively as follows: material production,water conservation,conservation soil,purifying environment,regulate the temperature and biological diversity.The value assessment of forest system service function is basically similar to the method of evaluating the value of the general ecosystem.The ecological and economic role of the forest ecosystem uses a measure of value as a yardstick.According to the criteria of evaluation of forest ecosystem service function value,the evaluation process will be divided into more than six of its service function,each service function according to the actual situation analysis and selection of a dataacquisition method in the evaluation of the assessment methods are as follows:evaluation of forest ecosystem service function of market value method,shadow engineering method and the opportunity cost method,parameter method,value.The evaluation result has two kinds of service function values,which account for 24.5%and 23% of the total value of all service functions,two of which are the functions of water conservation and the service function of carbon fixation and oxygen release.The evaluation shows that Shandong yellow blue economic zone to the forest water conservation service value in all the forest service function value in the proportion of major,showed strong ability of water solid water forest ecosystem,water conservation ecosystem plays a very important role in the ecosystem of the forest ecosystem.The value of forest ecosystem conservation in Shandong blue economic zone is RMB.The total service function value is RMB.The total value of forest ecosystem water conservation value and forest ecosystem service function is24%.The value of water conservation for forest ecosystem in the Yellow River delta high efficiency ecoology economic zone in Shandong is RMB.The total service function value is RMB.The total value of forest ecosystem conservation water value and forest ecosystem service function is 25%.(2)evaluation of service function of wetland ecosystemWetland ecosystem is the kidney of the earth,and the value assessment of wetland ecosystem service function is an important part of the evaluation of ecosystem value.The wetland system in the study area is divided into the following types according to the causes of formation and geographical location: wetland types near the coast,estuaries,rivers and lakes,and the types of reservoir wetlands constructed by artificial way.According to the related scholars and the characteristics of the research area,the wetland ecosystem service function is evaluated according to the following aspects.It includes carbon fixation,water regulation,regulating flood regulation,purifying value,habitat value,and protecting bank protection against storm value.The value of wetland ecosystem services in Shandong blue economic zone is about RMB,and the proportion of material production is 81%.The second place is the regulating functionof wetland ecosystem,accounting for 17%.The value of wetland ecosystem service function is about $53% in Shandong the Yellow River delta efficient ecology economic zone.The proportion of material production value is about 53%,and the proportion of regulatory function value is about 41%.(3)evaluation of the service function of farmland ecosystemFarmland ecosystem is one of the most important ecosystems in the world.It is also a natural artificial composite ecosystem directly managed by human beings and meeting human needs.It provides 66% of the world's food supply and has great ecosystem service value.The value of farmland ecosystem service function has two sides.On the one hand,opportunity is beneficial to human or environmental output.On the other hand,ecosystem service function has negative benefit value.The service function of farmland ecosystem in Shandong blue economic zone should include product supply,carbon fixation,oxygen production,water conservation,air quality control,soil erosion prevention and soil nutrition maintenance.The total value is: yuan.The largest proportion of various service functions is carbon fixation,the proportion of which is 92%.The evaluation of the function value of the ecosystem service function of the high efficiency ecology economic zone in the Yellow River delta of Shandong is RMB,and the ratio of carbon fixation value is 82%.(4)value assessment of marine ecosystem service functionMarine ecosystem is the origin of the earth's life.It's a wonderful and wonderful natural resource on the earth.There are endless mysteries in the ocean.All kinds of mysterious marine creatures are abundant treasure on the earth.The total value of the marine ecosystem is yuan,and the service function of the large proportion is the value of food supply,the proportion of which is 55%.
