河南省野生植物资源及其可持续利用

根据河南省新的植物区系资料对其植物资源进行了分类与数量统计,并提出了可持续利用的途径.结果表明,本省植物资源有15类,其中用材植物474种,野生水果144种,绿化、观赏植物534种,淀粉植物140种,油料植物291种,纤维植物271种,药用植物1172种,牧草及饲料246种,芳香油植物143种,鞣质植物259种,树脂及橡胶植物29种,蜜源植物171种,野菜植物150种,有毒植物80种.实现植物资源的可持续利用,需要进一步调查研究,建立植物资源信息系统;制定切实有效的利用与保护并重的措施,包括适时适量采集,综合利用,建立植物资源基地,科学有效地开发利用植物资源;以植物生境及其多样性保护为基础,以重点物种为主要保护对象,建立完善的自然保护区网络;同时还要加强宣传教育和法制建设,提高公众对植物资源保护的自觉性.
