摘要
在生态破坏较严重的浙西石灰土山地,经三年的生态重建模式定位试验,明确了银杏、日本甜柿、板栗、枇杷、梨树和黑麦草为石灰土山地适生的生物种群;以此设计的果-草生态重建模式,具有改善生态、提高肥力、增加收入的良好效益,可在北亚热带石灰岩地区推广.
In the limestone hilly region of West Zhejiang belonging to north subtropical zone, where the virgin ecological environment was disturbed, a location test which consisted of ecological models was established within a 3year period.It was demonstrated that plants like ginkgo,sweet perimmon, Chinese chestnut, loquat, pear and rye glass are suitable for the area. The rebuilt ecological model consisting of these five biotic populations was effective in improving the ecological environment, raising the soil fertility and increasing income, thus can be applicable in the north subtropical limestone area.
