以福建省闽清县高岭土采矿废弃地研究为例,在对矿区生态环境调查的基础上,选择马尾松、胡枝子、桃金娘、茶树、绿竹、香根草、五节芒等几种植物作为植被恢复的的先锋植物,采取不同的试验处理方法.经过3 a时间,对其生长状况进行测定.结果表明:高岭土矿山分布区植被贫乏;矿区废弃地土壤养分缺乏、土壤pH值较低,它们是植物生长的重要限制因素;选择马尾松、茶树、绿竹、香根草、五节芒进行乔灌草相结合的植物群落配置,结合熟土回填的处理,有利于植物较快生长,取得较好的生态效益和明显的经济效益.鉴于这几种植物在亚热带的广布性,它们是亚热带高岭土矿区进行植被恢复的首选植物. 相似文献

香根草在土壤改良和水土保持中的作用 总被引：22，自引：0，他引：22
香根草作为一种理想的水土保持植物具有许多优良特性，目前正在热带和亚热带地区广泛推广种植。本文通过盆栽和大田两方面试验观测了香根草在土壤改良和水土保持中的作用。结果表明，种植香根草后可使强酸性土壤的可交换性铝含量下降，并使土壤ｐＨ值、有机质、全氮、速效氮和钾以及总孔隙度等都有不同程度的增加。与对照区相比，香根草区的径流量和土壤侵蚀量分别下降了６０％和９３％，而土壤含水量上升４％～４２％不等。香根草还可较好地改善果园小气候，使果园生态系统内的士温、气温和空气湿度等都朝着有利于果树生长发育的方向变化。 相似文献

恢复人工植被是祁连山自然保护区矿区废弃地修复的主要手段,经过近5年的修复,矿区废弃地修复区地上植被盖度明显提高,但关于作为评价土壤修复效果重要指标的土壤动物群落变化的认识还很有限。以祁连山自然保护区典型煤矿废弃地为研究对象,采用野外调查的方法对比研究了煤矿修复区和毗邻区（原始地貌）大型土壤动物分布特征及其影响因素。结果表明：（1）修复区植物丰富度、生物量、盖度及土壤粗砂、有机质、全氮含量均显著低于毗邻区（P<0.05）,而土壤水分、细砂、黏粉粒、全钾和全磷含量差异不显著（P>0.05）。（2）修复区土壤动物活动密度和多样性均显著高于毗邻区,修复区和毗邻区土壤动物均以蝗科（12.7%和55.7%）和蚁科（14.4%和49.6%）为主;进房沟、水磨沟和柳树沟煤矿修复区及毗邻区土壤动物群落相似性分别为39.9%、52.9%和43.4%。（3）土壤有机质含量是影响煤矿修复区和对照区捕食性土壤动物群落变化的主要因子,而草本物种数和土壤粗砂含量是影响植食性土壤动物群落变化的主要因子。总之,人工修复后煤矿废弃地修复区土壤动物个体数均高于对照区,部分矿区修复生境类群丰富度及多样性已经超过了毗邻区,这表明蚂蚁、步甲和蝗虫等地表节肢动物对煤矿矿区覆土恢复植被和封禁等措施驱动的植被和土壤环境变化响应敏感。因此,还需要优化植被及土壤修复模式,提高土壤动物多样性及多功能性,使矿区废弃地生态环境能够得到快速修复。 相似文献

陕西黄土高原土壤干层对植树造林的影响 总被引：20，自引：10，他引：10
根据野外考察和陕北、关中土壤含水量测定,讨论了陕西黄土高原土壤干层的分布范围及其对恢复植被的影响。资料表明,黄土高原土壤干层分布普遍,向南分布已达关中平原地区。不同植被带土壤干层发生原因有一定差别,干层发育程度有明显不同。在生态环境建设中,应根据不同地区土壤干层发育强度差别恢复不同类型的植被。在以往划分的延安以南的落叶阔叶林带,土壤干层发育较轻,可采取草、灌、乔木相结合的措施逐步恢复森林植被。在延安到长城之间的森林草原带,土壤干层发育严重,应当先发展草灌植被,后恢复森林草原植被。在长城以北的草原带应自然恢复草原植被。在土壤干层发育严重的地区,造林一般不能带来环境效益与经济效益,反而会导致深部土壤水分的过量消耗等不良后果,是不适于造林的地区。在黄土高原退耕还林还草的生态建设中,不论是发展人工林还是发展草灌为主的植被,都不宜选择耗水多、生长快的植物种,而应当发展生长适中偏慢的乔、灌、草种。 相似文献

煤矸石山不同植被恢复模式对土壤养分的影响——以山西省河东矿区1号煤矸石山为例 总被引：9，自引：0，他引：9
对2009-2011 年山西省河东矿区不同植被恢复模式下土壤养分进行了检测分析,并对其环境影响因子进行了研究.结果显示：(1) 随着矸石山植被恢复年限的增加,煤矸石山地温显著降低,植物多样性增加,盖度和生物量不同程度提高.(2) 经过3 年植被恢复的矸石山土壤速效磷和速效钾的改良效果达到全国土壤普查3 级水平;恢复土壤碱解氮和有机质含量为11.94 mg·kg-1和7.69 g·kg-1,改良效果不显著.紫穗槐模式对土壤速效磷的改良效果较好;紫穗槐-高羊茅-紫花苜蓿模式有利于碱解氮的积累;高羊茅-紫花苜蓿模式对速效钾和有机质的改良效果最佳.(3) 矸石山坡度和地温与土壤养分呈显著负相关;紫花苜蓿盖度与碱解氮、速效钾和有机质含量呈显著正相关;植被平均生物量和高羊茅盖度的提高有助于土壤养分的改良效果.煤矸石山植被恢复宜采取以草开路,在生态环境条件有所改善基础上,走草、灌、乔相结合的构建模式. 相似文献

香根草是世界上公认的水土保持植物,但作为抑螺植物材料尚属首次。研究了香根草在4种典型生境条件下的年生长格局及抑螺效果。结果表明:香根草具极强的分蘖能力,每丛分蘖数在9株以上,能在1年内成为优势草本群落;在水肥条件好时,分蘖数和高生长明显增加;在水肥受限时,高生长受限,但地下生物量明显增加;香根草叶24h、48h的LC50(半致死浓度)值显示,其灭螺效果低于夹竹桃叶,而高于枫杨叶。综合分析表明,香根草能成为山丘型血吸虫疫区最理想抑螺草本植物,可在同类地区推广。 相似文献

科尔沁沙地围封草地种子库特征 总被引：43，自引：9，他引：34
科尔沁沙地自由放牧草地围封7a后土壤种子库中植物种类有25种,其中一、二年生植物 19种。土壤种子库密度 3314粒·m-2,其中,黄蒿(Artemisia scoparia)、狗尾草(Setaria viridis)、三芒草(Aristida adscensinis)等一年生植物种子占总数的95.3%,而多年生植物仅占4.7%。若以单子叶和双子叶植物统计,单子叶植物种子数占14%,双子叶植物的种子数占86%,其中豆科植物仅占2.4%。土壤种子库植物的种子数与其相应植物在植被中出现频率有明显的相关性。从种子库组成分析,围封7a的草地植被维持在黄蒿-杂类草混合植被阶段。围封草地对农牧生产方式转换频繁的科尔沁沙地草地植被恢复起着"种子岛"作用,它们的存在可以缩短周围被干扰草地恢复的时间,应该加强围封草地的管理利用研究。 相似文献

太阳光照是植物光合作用的必要条件。喜光植物(如马尾松、侧柏、桉树)必须有充足的阳光才能生长或长得良好,它们一般生长较快,叶小及节间短。而喜阴植物(如冷杉、黄扬、春兰)其生长过程也并非不要阳光,只不过它们喜欢在蔽荫环境中生长,它们的叶往往大而薄。枝叶较密,一般生长缓慢,寿命较长。纵使长年生长在阴暗山洞里的一些植物。也需要一定的阳光。 相似文献

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world＇s largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing. 相似文献
