摘要: <正>对金沙江干热河谷上游鹤庆段退耕地人工恢复植被川楝Melia toosendan初期的1~4a生物量以及林下草本层物种多样性进行了比较研究。结果表明,川楝对干热河谷环境有较强的适应性,早期生长良好、郁闭度高、积累的生物量大。但不同坡向之间存在较大的差异:南坡上的单株以及各器官的生物量干重均较北坡高;南、北坡上川楝的单株、干、枝、根生物量分别为25.246±0.586kg、14.986±0.203kg、4.634±0.212kg、5.626±0.223kg和16.580±0.206kg、8.544±0.087kg、2.895±0.067kg、5.141±0.074kg。在单株及各器官含水率方面,南、北坡上川楝人工林除了根部有极显著差异P<0.O1,其他部分差异均不显著。林下物种多样性的比较研究表明,川楝林的种植改善了退耕地中植被的生长环境,林下植被多样性及丰富度均得到了较大程度的提高。

Abstract: After the collective forestry property rights system in Fujian was adjusted, the functions of forestry production and the ecosystem construction became great in the state-owned forest farm of collective forest district. Sanming state-owned forest farm in Fujian was chosen as an example in this study. The potential problems were analyzed in the state-owned forest farm development. The scientific definition of the state-owned forest farm type was put forward. At the same time, this paper provided some measures, e.g., strengthening the nation investment, adjusting the distribution policy of the state-owned forest farm, etc., to realize a well balance of the multi-value mode in the value orientation of the policy.
