基于层次分析法的水土保持牧草筛选评价

Grasses for Soil and Water Conservation Selected by Analytic Hierarchy Process

摘要

摘要:
目的筛选适宜福建省种植的水土保持型牧草，为福建省水土流失区域治理的草种选择提供参考。
方法在水土流失严重的长汀地区选取11个草种，通过测定出苗率、成活率、覆盖度、枯落物浸水容量、根系重等水土保持特性指标，运用层次分析法和模糊数学法对试验品种进行综合评价，筛选福建省水土保持适宜牧草。
结果试验区内表现优或较优的草种有百喜草、闽引圆叶决明、闽草1号狼尾草、闽牧6号狼尾草、大翼豆、葛藤；表现良好的有红象草、钝叶决明、扁豆、含羞草；表现较差的有福引圆叶决明1号。
结论禾本科属的百喜草、闽草1号狼尾草、闽牧6号狼尾草，豆科属的闽引圆叶决明、大翼豆、葛藤较为适合福建长汀及周边相同气候条件的水土流失地区种植。

Abstract:
Objective Varieties of grass were evaluated for soil and water conservation in Fujian area.
Method In Changting, the area where soil erosion and water conservation have become a serious concern, 11 varieties of grass for forage were screened according to their characteristics on the rates of germination, survival, coverage, and litter water-holding capacity as well as the weight of root mass. Analytic hierarchy process and fuzzy mathematics method were applied for the selection of best adaptable grass in the area.
Result Paspalum notatum Flugge, Chamaecrista rotundifolia cv. Minyin, Pennisetum americanum×P.purpureum Mincao 1, Penniseturn americanum×P.purpureum cv. Minmu 6, Pueraria lobata, and Macroptilium atropurpureum, were considered superior or desirable varieties. Pennisetun purpureum cv. red, Cassia obtusifolia, Lablab purpureus (L.) Sweet, Mimosa pudica exhibited good performance, whereas, Chamaecrista rotundifolia cv. Fuyin 1 did not perform well.
Conclusion The gramineous grass, Paspalum notatum Flugge, Pennisetum americanum×P.purpureum Mincao 1, Penniseturn americanum×P.purpureum cv. Minmu 6, and leguminous grass, Chamaecrista rotundifolia cv. Minyin, Pueraria lobate, Macroptilium atropurpureum, appeared to be suitable for cultivation in the areas around Changting.
