Research On The Increase Of Urban Construction Sites To The Decrease Of Rural Construction Sites Linking

China has a vast territory,rich in land resources,according to the results of the second national land survey:a total of 20.31 million mu of arable land,of which 15.61 billion mu of basic farmland.At the same time,the population problem has always been the overall,long-term and strategic problem facing our country.By the end of 2016,the total population of mainland China was 1.382 billion(including 31 provinces,autonomous regions,municipalities and the Chinese People's Liberation Army active duty,excluding Hong Kong,Macao and Taiwan And overseas Chinese),so the total resources,the relative lack of per capita resources,reserve resources are particularly scarce,the contradiction between the people and more is also very prominent."13th Five-Year Plan" period is the period of industrialization and urbanization in China,and it is also a critical period of building a well-off society in an all-round way.With the further development of economy and society,the future development of cities and towns will inevitably meet the needs of cultivated land Land demand,land supply and demand will become increasingly sharp contradictions,arable land protection task will be very difficult.At the same time,for rural areas,the impact of urbanization process,more and more migrant workers,the rural population to an annual average of more than 10 million scale into the town,and village planning often can not keep up with the overall planning The lack of unified planning and requirements for the construction of village houses,leading to rural homestead too large too scattered and disorderly building a long time,the contradiction between urban and rural land is deepening.To fundamentally solve the contradiction between urban and rural land use,urban and rural development must be planned rational planning of urban and rural construction land layout,in strict accordance with the overall planning of land use requirements,the rural area of construction area is too large and scattered rural settlements to withdraw the village and gradually finishing For the construction of urban and rural economy,to ensure that the reduction of rural land construction area and the number of urban construction to increase the part of the line to avoid the use of various types of land resources is too imbalanced situation,and finally optimize the urban and rural areas overall arrangement.Urban and rural construction land to increase or decrease the hook system,as an effective mitigation of contradiction between cultivated land protection and urban construction land tensions of expediency,positive performance and negative problems coexist.At present,the empirical analysis of the increase and decrease of urban and rural construction land is focused on the feasibility analysis of the project,the exploration of rural residential management methods,and the development of urban and rural construction land according to the problems exposed during the actual operation of urban and rural construction land The theoretical research and empirical research on the performance evaluation system of hook performance are rare,especially the establishment and evaluation of landscape performance evaluation index.This paper,based on the analysis and research of the theory,the comprehensive application of feedback-control theory,sustainable development methods and theoretical achievements,the current urban and rural construction land use change in the actual research,through literature research,field investigation,qualitative and quantitative analysis As well as mathematical model method and a series of research methods,from the economic,social,ecological and landscape four aspects of the selection of evaluation indicators,construction of urban and rural construction land to increase or decrease the performance evaluation system,and Shandong Province Linyi County increase or decrease project as an example,On the one hand the performance evaluation system of the project objective and impartial evaluation,on the other hand found the problem and analyze the reasons,targeted reform proposals for the government's project investment and decision-making to provide the basis for improving and improving the performance of the project.
