Abstract: Based on the latest 1:50000 topographic map, the 1:100000 slope gradation map is drawn out and area calculation is made. The direct solar radiation in typical sites of the district is measured and calculated,and the variation curves of annual flux of direct solar radiation on various slope directions with the change of slope grade are drawn out. Differences of radiation factors for agricultural production of this district are analyzed accordingly.

Key words: mixed conifer-broadleaf forest, stem sap flow, environmental factor, dry and wet seasons, Dinghushan.
