大数据驱动下全域土地综合整治评估思路及其应用方向

全域土地综合整治是国家层面的战略部署,更加强调"山水林田湖草是一个生命共同体"的整治理念.基于土地利用调查、统计年鉴等传统数据的整治评估已经难以实现对全域土地综合整治的系统评估.大数据时代的到来,为全域土地综合整治评估与决策提供了新的思路.研究立足全域土地综合整治的发展背景,基于大数据的主要特征,分析大数据驱动全域土地...

Thinking and Application Direction of Comprehensive Land Consolidation Evaluation Driven by Big Data

Comprehensive land consolidation is a national strategic plan,which more emphasizes the concept of"mountains,rivers,forests,farmland and lakes are a community of life".Based on the traditional data such as land use survey and statistical yearbook,it is difficult to realize the systematic evaluation of comprehensiv e land consolidation.With the advent of the era of big data,it provides new ideas for comprehensive land consolidation assessment and decision-making.Based on the development background of comprehensive land consolidation and the main characteristics of big data,this paper analyzed the path of big data driving the transformation of comprehensive land consolidation concept,sorted out the main types of big data supporting comprehensive land consolidation and the ways of big data acquisition and processing.We also clarified the main task requirements of comprehensive land consolidation driven by big data and proposed the general framework for dynamic evaluation of comprehensive land consolidation.Also,the application direction of big data in dynamic evaluation of comprehensive land consolidation is further clarified,so as to provide a reference for promoting the pilot work of comprehensive land consolidation.The main conclusions are as follows:(1)big data drives the transformation of comprehensive land consolidation assessment to"human-oriented",comprehensive assessment,dynamic monitoring assessment and public participation assessment:(2)there are 10 types of big data supporting comprehensive land consolidation,focusing on the feasibility assessment before comprehensive land consolidation,monitoring assessment during consolidation and benefit assessment after consolidation;(3)the application direction of big data in the"pre-mid-post"evaluation of comprehensive land consolidation includes 10 items(e.g.,farmland fragmentation evaluation),8 items(e.g.,the implementation progress evaluation of consolidation tasks),and 10 items(land use benefit evaluation),respectively..
