毛乌素沙地野生观赏植物资源及开发利用研究

Study on the Resources and Development Use of the Wild Decorative Plant in Maowusu Sand

经野外调查和室内资料统计,毛乌素沙地野生观赏植物共有83科、170属、499种(含变种)。引种试验表明,一些野生观赏植物或形态各异,迎霜傲雪;或花色艳丽,五彩缤纷,具有较高观赏价值。尤其是耐寒、耐旱、耐瘠薄,抗风沙,适宜在毛乌素沙区自然条件下推广种植。本文对沙区可用于城镇绿化的蓝刺头Echinops latifolius、罗布麻Apocynum venetum16等种主要野生观赏植物进行了比较详细地论述,并提出了可行性利用与保护措施。

Through outdoor investigation and indoor data statistics, it was found that wild plants with decorative values occourring in Maowusu sandy area belonged to 83 families, 170 genus and 499 species （including variants）.
