湖北贫困地区旅游开发优势及现实意义——以鄂西北地区为例 总被引:6,自引:0,他引:6
以鄂西北地区的襄樊市、十堰市和神农架林区为例,分析了该区的区位条件和社会、经济发展态势,旅游资源特征,旅游环境现状及其开发优势,阐述了贫困地区旅游开发规划对扶贫工作的促进作用和扶贫旅游的现实意义。本区的多数县市处于山地环境,地形崎岖,交通受到限制,经济发展相对滞后,扶盆任务依然艰巨,本区旅游资源丰富多彩,有些资源的品位也很高,可以总括为“531优势”。即人文旅游资源的五大文化特点-楚国发祥地(楚文化),三国之源(三国文化),流放文化,道教文化,郧阳猿人(古人类文化),形成明显的锁定效应;自然旅游资源的三大品牌-纳入“世界自然保护区网”的神农架,在国内外有一定声誉的郧县恐龙蛋化石基地,正在规划的武当山国家级地质公园,一处国家级风景名胜区-自然与人文景观相得益彰的“隆中风景名胜区”,其资源环境优势在于,自然生态优美,环境污染轻,空气质量好,气候适宜,土特产品丰富,对这些旅游资源进行科学合理的开发利用,并按照“PPT”战略实施扶贫计划,将有力促进本地区经济发展。 相似文献

Arsenic uptake by arbuscular mycorrhizal maize (Zea mays L.) grown in an arsenic-contaminated soil with added phosphorus 总被引:1,自引:0,他引:1

The effects of arbuscular mycorrhizal (AM) fungus (Glomus mosseae) and phosphorus (P) addition (100 mg/kg soil) on arsenic (As) uptake by maize plants (Zea mays L.) from an As-contaminated soil were examined in a glasshouse experiment.Non-mycorrhizal and zero-P addition controls were included.Plant biomass and concentrations and uptake of As,P,and other nutrients,AM colonization,root lengths,and hyphal length densities were determined.The results indicated that addition of P significantly inhibited root colonization and development of extraradical mycelium.Root length and dry weight both increased markedly with mycorrhizal colonization under the zero-P treatments,but shoot and root biomass of AM plants was depressed by P application.AM fungal inoculation decreased shoot As concentrations when no P was added,and shoot and root As concentrations of AM plants increased 2.6 and 1.4 times with P addition,respectively.Shoot and root uptake of P,Mn,Cu,and Zn increased,but shoot Fe uptake decreased by 44.6%,with inoculation, when P was added.P addition reduced shoot P,Fe,Mn,Cu,and Zn uptake of AM plants,but increased root Fe and Mn uptake of the nonmycorrhizal ones.AM colonization therefore appeared to enhance plant tolerance to As in low P soil,and have some potential for the phytostabilization of As-contaminated soil,however,P application may introduce additional environmental risk by increasing soil As mobility. 相似文献

江南多山丘,占总面积70%以上。红壤丘陵及割切阶地广泛分布于山间盆地与河谷平原两侧。这一带人口密集,主要从事单一粮食生产,广大丘陵只作为樵材、取肥的场所。致使天然植被荡然无存,甚至发生严重水土流失。试点证明:立足沟谷水田增产的同时,开发整治山丘。在保蓄当地降水的基础上,采用农、林、牧、渔业措施,全面综合开发山丘;并选定1~2项主导商品生产项目,进行开发。建成立体农业生产体系,从而获得明显的生态、经济与社会效益。 相似文献
