| 摘 要： | 在各树种不同配置方式试验研究基础上,提出了风沙区构建多样性、稳定性农防林的框架,结果表明,营建针叶常绿林带或针阔混交林带在防护效果和观赏价值上皆优于纯阔叶林带.针对风沙区农防林单纯林带比重大、空间分布欠合理等问题,提出景观补救方法引入新"斑块"扩大混交比例,增加观赏价值高的树种种类,采取人工抚育、修枝等措施创造适宜的观赏环境.

| Abstract: | The farmland shelterbelt frame of structure diversity and stability put forward on the basis of experiments. Protection effect and value of viewing and admiring of the needle leaf evergreen forest belt and the mixed broadleaf and needle leaf forest belt are superior to the pure broadleaf forest belt. In the light of pure forests and irrational spatial structure in the farmland shelterbelt in sandy area, the landscape remedies are also put forward, introducing new patches for enlarging ratio of mixed forest, increasing trees species of high value in viewing and admiring, creating suitable environment by artificial tending and pruning. |
