摘　　要：针对黄土丘陵区生态环境建设与水土资源开发利用的需要，在该区的主体部位──坡地上，应用多台自记监测装置；对坡地不同坡向、坡位，近地层的太阳辐射、气温、地温、土壤水分、以及以牧草为主的植被生产力的分布变化，进行了较为系统的实地观测研究，并分析揭示了它们的一些基本变化规律，对坡地的合理开发利用可提供气候与土壤生态学依据。According to the needs of erecting eco-environment, exploitting and utilizing soil and water resources, authors had systemly surveyed several near to ground factors, such as sunlight, air and soil temperature, soil moisture, the distribution and stain of plant productivity which mainly consisted of grasses, by using several auto-count instruments in several sloping fields and in different site of the sloping fields. The authors also analyised and announced some of these basic variety law which could provide a few of climate-ecology basis. Those work above would benefit to reasonaly expoit and utilize sloping fields.
