Research Abstract

Crop fields in hilled area are suffered from various obstacles which shield solar radiation. Reduced radiation affects the environment including micro-climate, soil moisture and soil temperature. First, the conditions of surrounding obstacles were studied by using fish-eye photograph. The changes of plants morphology and growth rates were analyzed to determine the gap ratio in the space. Second, production reduction induced by the environmental change was observed and quantified by applying logistic model to simulate the crop growth rate. Third, water consumption in crop filed under the condition of edge-effect.was quantified. Using two dimensional model water and heat flow in the soil. were simulated. To specify the upper boundary condition, solar radiation transfer model was established clarifying the energy condition on the surface of crop filed. Fourth, these newly established models were checked their efficiency at the small sloped model fields constructed in the experimental field. The simulated result showed good agreement with the observation. Finally, the application study was conducted on estimating the effect of forestation on environmental changes at crop fields at the forest edge in arid area. Using the result, optimal water manage system for was proposed.
