Study On The Impact Of Land Remediation On NDVI

Land consolidation played an important measure in coordinate the contradiction between people and land,and played an important role in those aspects,optimal allocation of land resources,improved of agricultural production conditions and ecological security construction.The impact of land consolidation on ecological environment has become a hot spot recent years,and it was a precondition that realized the intensive utilization of regional land resources,regional ecological environmental improvement and the social and economic sustainable development of ecological environment.Vegetation was an important part of terrestrial ecosystem,and was one of the most important indicators of ecological environment.Therefore,NDVI was taken as ecosystem,45 land consolidation areas which have been completed in Yunnan Province were selected as study areas,MODIS NDVI data from 2001 to 2015 was selected as study data,and paired sample T test method was selected as study method in this paper,explore the influence of land consolidation affect NDVI from the two aspects,within the project area and periphery of project area.The main conclusions were as follows:1)In this paper,the quantitative analysis parameters based on NDVI were constructed in evaluation of the ecological status of land consolidation.2)NDVI had no significant difference after land consolidation in the project area,but the regional NDVI change become more stable.There were differences between result of this paper and the existing land consolidation report that land consolidation will improve the ecological situation in the project area.3)Land consolidation activities had stimulative effect on NDVI that a certain range outside the project area,the stimulative effect presented a trend that first increased and then decreased,and the maximum effect appeared at about 8km outside the project area.
