摘　　要：浙江省是我国南方典型丘陵山区省,低丘缓坡土地的主要土壤类型为红壤土。但是,现在我国南方经济较发达地区如浙江,面临着土地占补平衡的补充耕地质量不高、缺水的难题。基于此,本试验通过对天然降水循环规律的研究,采用了长系列气象资料分析、实地数据采集观测、土壤结构分析、水量平衡分析、材料试验分析、水稻种植试验等方法,解决了南方丘陵区旱地的灌溉问题,提高了补充耕地质量,提升了土地产能,找到破解土地资源制约经济发展瓶颈的一种途径。Zhejiang Province belongs to typical hilly areas with red soil covering nearly all low and gentle slopes. However, those provinces like Zhejiang in South China face the challenge brought by low quality of supplement farmland and water scarcity, although the area is well-developed. Taking the above into consideration, an experiment is conducted for examining law of natural rainfall cycle, by means of long series meteorological data, collection and observation of on-site information, soil structure analysis, water balanced analysis, material text and rice planting. The unit area micro-circulation of natural rainfall is found that help to address irrigation needs in dryland of hilly areas. It improves the quality of supplement farmland and its productivity, which is crucial for the beneficial use of land resources for economic development in the region.
