At present, China vigorously promots the land comprehensive remediation projects,butbenefit evaluation of the present stage of our country is mainly concentrated in economicbenefit evaluation, pay attention to the improvement of land productivity,pursue themaximization of benefits, the qualitative and quantitative evaluation of landscape ecologicalbenefits is still in the fuzzy stage, therefore, the land consolidation project benefit evaluationof land consolidation based on landscape pattern is important. Meanwhile, the differentregional land renovation project on the landscape pattern characteristics and comprehensivebenefit evaluation results have obvious difference, comparing the different terrain of project isbeneficial to the determination of evaluation standard and evaluation system, perfectingproject construction and project location of reasonable selection has reference significance.In the study of landscape pattern characteristics of land remediation project, thispaper selects the Yiyuan county land consolidation project’s arable land, village, garden landand grassland which located in the hilly area and Dingtao county land consolidation project’sarable land and the village doing landscape characteristics analysis. Secondly, comparativeanalysis of Yiyuan county land consolidation projects and dingtao county land consolidationprojects’s land use landscape pattern, finally it is concluded that: the number of patch,patchdensity and landscape shape index of hilly area was significantly higher than large plains,visible terrain and slope on the effects of landscape pattern. Plains land remediation is morelikely to decrease in the class, landscape heterogeneity index decreased, the largest patchindex increased significantly in plain area, arable land has the obvious landscape advantages,hilly landscape has large degree of fragmentation and small aggregation index, the structure ofland use is different,it has a better Spatial distribution than plain area.According to the different regional land consolidation comprehensive benefit analysisof the evaluation results, research shows that, Yiyuan county land remediation projectcomprehensive benefit score is82.36, according to the evaluation standard for the good level,Dingtao county land remediation project comprehensive benefit score is79.82, based on theevaluation standard for the general leve,it shows that the land consolidation benefit in thehilly areas is potential higher than plain area.The social benefit of hilly area is85.88, thesocial benefits of the plain area is84.65, social benefits are basically identical; Hilly area landscape ecological benefit is74.91, plain area landscape ecological benefit is82.11,itillustrates that plains area has high landscape ecological benefits; Hilly area economicbenefits is85.66, economic benefits of plain area is76.46, the hilly areas have highereconomic benefit.
