摘  要:
在江苏省里下河地区的湿地开发过程中 ,充分利用了林、农、渔、副业的复合经营 ,取得了显著的经济、生态和社会效益。采用灰色关联分析方法 ,探讨不同密度林分内间作物产量与林内小气候因子的关联度。结果显示 ,林木展叶后 ,冠下光照强度明显减弱是造成小麦减产的主要原因。用GM ( 1 ,1 )模型建立了林下间作物产量预测方程 ,并为确定合理的林分初植密度提供依据。

摘  要:
In recent years, a lot of agroforestry systems have been developed in Lixiahe region, Jiangsu province. Economic, ecological and social profits have also been achieved by exploitation and uses of wetland resources. I n this paper, authors have used relationship analysis to investigate relations b etween microclimatic factors and the yield of wheat interplanted under forests w ith different densities. The results showed that the decrease of radiation was t he key factor that caused the decrease of wheat yield. A grey system model was d eveloped to predict interplanted wheat yield and determine appropriate stand den sity in agroforestry systems.
