Progresses in Research of Evaluation Index System and Its Method on Arable Land Intensification: A Review
摘要
Abstract
Arable land intensification is a necessary choice to face the multiple pressure of socio-economic development,limits of land use quantity,population growth and technology improvement.Started with the interactive framework among arable land intensification,agricultural sustainable utilization,ecological protection and grain security,this paper summarized the current indicator system of arable land intensification,proposed the evaluation index system of intensive cultivated land use based on interactive framework,and reviewed the existing technology,method and their related achievements.Based on above analysis,the next hotspot and development trend of future study were proposed.The result showed that arable land intensification,agricultural sustainable utilization,ecologic-environment and grain security play a role of mutual improvement mainly or with the dual influence of positive or negative.The current indicator system of arable land intensification can be considered mainly in different view of frequency indices,input indices,output indices,potential indices,gap indices,comprehensive indices,intensity indices,energy indices,etc.The evaluation index system of intensive cultivated land use based on interactive framework included some basic indexes such as the average labor input,average fertilizer input,average pesticide input,irrigation index,etc.Indexes which affecting agricultural sustainable utilization mainly included food security factor,non-farming index,cultivated land area per capita,etc.And indexes strongly correlated with grain safety included multiple cropping index,stable production index,grain yield per hectare,per-cultivated land production,etc.Nevertheless,the further choice and revision of the indexes should be considered according to the different study region and scale in specific condition.Within all the research method relating those indices,the paper found that frequency indices were the hotspot of remote sensing focused on arable land intensification.Potential indices were researched mainly by model simulation.On the contrary with the abundant research achievements of yield gap,harvest gap got little concern in those gap indices today.In addition,comprehensive measuring model of intensity also was the main and common method to appraise the arable land intensification.It is noteworthy that some other related research results can be utilized further to appraising the arable land intensification.The type of arable land intensification indices demonstrates the development trend of diversified characteristic.Besides,the comprehensive integration of new method and new technology should push forward in the future.关键词
