Research On Cultivated Land Pressure Assessment System And It's Design

Cultivated land resources is the material basis for human survival and development,and it is the most fundamental guarantee for the security of grain supply in the country or region.It plays an irreplaceable and fundamental role in the sustainable development of agriculture and national economy.China's economic development into the new normal state,agriculture is in the transformation and upgrading period,how in the 'Internet + agriculture' information age assessment of the region's Cultivated land resources to ensure the safety of food supply,to achieve sustainable and coordinated development of human land for the current policy Under the guidance of the future development of targeted decision-making information to make important.Based on the previous research on the evaluation of regional Cultivated land pressure,this paper draws up the research results and expands the evaluation model of Cultivated land pressure.It mainly includes per capita grain consumption demand,grain yield index and grain sowing ratio index of Cultivated land pressure evaluation model.The principle of Cultivated land pressure evaluation is introduced.Based on the model of Cultivated land pressure expansion and the principle of evaluation,the design of auxiliary decision support system is used as the guiding ideology to analyze and design the Cultivated land pressure evaluation system.The system designs the indicators of Cultivated land pressure,such as population index,per capita grain consumption demand index,grain sowing ratio index,grain yield index and Cultivated land area index.Based on the relevant decision-making,The pressure assessment model comprehensively measures the pressure of Cultivated land in the area,and evaluates the safety status of the Cultivated land resources and grain supply in the region,and makes corresponding explanations.According to the relevant comprehensive decision-making,the grain self-sufficiency rate can be calculated by the inverse reasoning of the Cultivated land pressure assessment model.The system is compiled with VC ++ and MATLAB,and Microsoft SQL Server 2008 is used as the database development platform to realize the comprehensive evaluation of regional Cultivated land pressure and the measurement of the index.The design of the Cultivated land pressure assessment system can be realized and the regional population development can be measured to provide information support for regional food allocation.The regional food consumption demand situation can be estimated to provide information support for future grain demand situation.The regional grain yield and Cultivated land area can be measured and the overall grasp Regional food production situation,for the supply of food security to provide information support;comprehensive assessment of regional pressure on Cultivated land,under the guidance of the current policy for the development of future targets to provide decision-making information.
