摘要
集雨绿化系统主要以土壤水分为纽带,把土壤 植物 大气这个连续的系统统一为一个有机整体.讨论目前在绿化方面正面对的土壤干化问题、土壤植被群落类型以及造林密度现存的问题.集雨绿化系统减少了对最限制植物生长的土壤水分因子的影响,是目前进行植被建设的比较优化的系统.
Water Harvesting Forestation System is mostly based on soil moisture ligament, It makes soil-plant-atmosphere consecutive system unite integer. Debating soil dry layer, model of soil vegetation community and forestation density are important problem in the forestation. Water harvesting forestation decreases vegetal plants limit of soil moisture infection .Water harvesting forestation system is better optimizing system in the constructed vegetation now.
