- Title:
- Studies on the Structure Installation of Farmland Protective Forest in Maowusu Sandy Area
- 摘要:
- 通过对毛乌素沙地不同类型地农田防护林结构配置与防护效益关系的调查测定与分析，结果表明：毛乌素沙地农田防护林类型可分为林带林网状、小片林、四块状林、复合型林等4种，最佳的农田防护林结构配置应该是林带走向同道路、渠系相结合，主带结构采用稀疏型或低度疏透型，副带结构采用低度疏透型或低度通风型，带间距在不同类型地风沙危害程度树木生长及农业要求上的差异而不同。
- Abstract:
- The investigation and analysis on the relation between the shelter installation and its protective function at different-typed land in Maowusu sandy ayes,shows that shelter forest there can be devided into 4 kinds,namely,shelter belt,small-ploted forest,lumpy forest and mixed forest:and the most reasonable structure is the combinatin between the shetlers and roads and channels.The major shelter can be of apatse type or of low density and the subones in low density or low-degreed ventilation,the distance among which come from the differences of damage degrees from sandy winds.forest srowth and agricultural necessities at different-typed zones.
