摘要
当今环境资源的高度开发利用,造成了严重的生态环境问题,而林草复合系统在改善生态环境和实现可持续发展方面具有巨大潜力,可作为一种重要的生态修复手段来加以推广应用。本文对最近5年国内外有关林草复合系统的光合特性、微气候效应、生物多样性、土壤功能等方面研究进行归纳与总结。针对目前林草复合系统生态效益研究中存在的问题和不足,提出今后的研究重点应放在林草复合系统的生态效益综合评价、生态系统固碳机理、土壤微生物遗传多样性、土壤修复机理及量化系统模型等方面。
At present,the highly development and utilization of environmental resources has caused seriously ecological and environmental problems,however,the silvopasture systems have great potential in improving ecological environment and realizing sustainable development which can be applied as a method of importantly ecological restoration.The present paper summarizes the home and abroad research about silvopasture systems in the recent five years which including photosynthetic characteristics,microclimatic effects,biodiversity and soil function etc.Based on the problems and defects existing in the research of current silvopasture systems,we consider that the future research of silvopasture systems should be focused on comprehensive evaluation of the ecological benefits,mechanism of carbon sequestration in the ecosystem,the genetic diversity of soil microorganisms,mechanism of soil restoration and the model of quantitative systems etc.
