Regional Evaluation of Meteorological and Ecological Resources including Mountainous Area

1. 选取松本盆地和伊纳河谷为研究区。对伊纳河谷西坡的一般气象因子（气温、土壤温度、降水、太阳辐射等）进行了测量。收集并整理了野外气象水文、地形、土地利用等基础资料。分析了山区地形因素与气象资料的关系。得到了局地和大尺度地形效应对气温日较差和递减率的影响。利用区域气象网的在线气象观测资料，采用DTS （the Days Transformed at Standard Temperature）方法预测苹果树的花期。由于预测值与实测值吻合较好，因此利用区域气象网在线资料是生态资源管理的有效措施。讨论了该区环境条件、土地利用与生产力的关系。因此，潜在生产力是指有利环境条件下植物的最大产量，在区域气象生态资源评价中具有重要作用。

1. Matsumoto basin and Ina valley were selected as this studying field. General meteorological factors (i. e. air temperature, soil temperature, precipitation, solar radiation and so on) were measured in the westem mountain slope of the Ina valley. The fundamental data of meteo-hydrological, terrain and land-use in the field are collected and recompiled.2. The relationships between topographcal factors and meteorological data in the mountain area were analyzed. The results that lapse rate and daily range of air temperature were influenced by local and large-scale topographical effects were obtained.3. Flowering day of apple tree was predicted from DTS method (the Days Transformed at the Standard Temperature) using on-line meteorological data, that was observed by regional meteorological network. As the predicted values were in close agreement with the observed, use of the on-line data on regional meteorological network was effective measures in the management of ecological resources4. It was discussed about relations among environmental condition, land use and productivity in the region. Consequently, potential productivity, which is the maximum plant production rate under favorable environmental conditions, takes an important role in regional evaluation of meteorological and ecological resources.
