Abstract

[Objectives] To explore the effects of spatial density of farmland shelterbelts on NDVI on the northern slope of Tianshan Mountains. [Methods] Taking the economic belt of the northern slope of the Tianshan Mountains as the research area and using the grid method, the spatial density distribution of farmland shelterbelts can be known. Combining the grid method with NDVI data, the average value of normalized difference vegetation index (NDVI) during the growing period of crops can be obtained. In addition, the protection benefits of the shelterbelts on crops were analyzed through comparing the growth of crops within the protection zone with and without protection. [Results] The grids with shelterbelt distribution were better than the grids without shelterbelt distribution, and the shelterbelt played a great role in promoting crop growth. In the middle stage of crop growth, the protection benefit of shelterbelt was significant. The spatial density of shelterbelts was unevenly distributed in the range of 0.6 to 0.8, and the protection benefits were poor. [Conclusions] It is expected to explore the effects of shelterbelts on crop growth at a larger regional scale, so as to provide a basis for the management and design of shelterbelts in the future, and to provide a theoretical basis for studying the protective effect of farmland shelterbelts on crops.
