The invention discloses a natural ecology compensation evaluation method in land consolidation planning. The natural ecology compensation evaluation method is realized through five steps of index weight determination, ecology risk cell division, evaluation factor quantitative classification determination, evaluation model construction and terrain gradient analysis and data classification. According to the method, before the index weight is determined, the expert evaluation of the index evaluation level is obtained, so that the index evaluation can be well evaluated, and the evaluation efficiency is effectively improved. According to the method, data storage can be well realized by utilizing a fishing net tool in ArcGIS10.5, and a list of all edges forming a TIN packet and information for defining TIN projection and measurement units are reserved. According to the method, a regional water circulation mode is changed through land consolidation, cross infection among crops is reduced through drainage and irrigat
