Abstract：The negative effect of shelter forest belts on crops exists objectively. According to the typical sampling investigation and illumination simulation test，this paper summarizes the variation rules governing the inter-relations among tree shading areas, shelter belt distribution, the width and height of the tree belt. And then put forward feasible selection and disposition of tree varieties for moderating contradiction between construction of roadsides revegetation and agricultural production.
