西气东输管道工程对沿线生态系统形成干扰,导致土壤质量下降。植被退化,生物多样性降低,风沙危害加剧等环境灾害,影响区域的生态安全.威胁到输气管道的安全运行。稳定性不同的生态系统对管道工程干扰有的反应不同.评价工程沿线生态系统的稳定性.有利于合理制定施工规范和开展工程后的生态恢复.对于保障区域生态系统和管道的双重安全具有重要意义。从生态系统受干扰后恢复能力的角度,在地理信息系统(GIS)平台支持下.采用图层投重-级别打分叠加模型,对管道沿线生态系统做稳定性评价。把生态系统稳定性按稳定性从低到高依次分为不稳定、欠稳定、稍稳定和稳定四个等级.结果发现沿线区域面积占15%的生态系统不稳定,52%区域欠稳定。针对稳定性低的盐土荒漠地区.沙质荒漠地区和棕漠土灌木荒漠三类地区,设计有利于促进生态系统恢复的友好环境构建对策。  相似文献

对黑河中游地区典型绿洲的土壤含水量与含盐量分析表明,在无灌溉情况下,绿洲及绿洲边缘过渡带表层土壤含水量水平分异明显,由绿洲区的20%左右递减到绿洲荒漠生态过渡带的2.9%。绿洲荒漠带土壤水分变化反映了人类利用绿洲水资源的程度,在绿洲地下水资源开发过度和绿洲边缘人类活动剧烈的区域均存在着生态裂谷,对绿洲生态系统的稳定极为不利。绿洲荒漠带土壤可溶性盐分含量的水平分异表现为绿洲土壤可溶性盐分含量比绿洲荒漠生态过渡带和荒漠区低;绿洲界外区不同荒漠类型土壤含盐量变化不同,在绿洲外围沙质荒漠区,土壤含盐量较低,在绿洲外围砾质荒漠(戈壁)区,土壤含盐量明显高于绿洲区;荒漠区土壤含盐量的垂直变化表明,含盐量最高的聚集层一般不在表层,而在40~60 cm的亚表层。受土壤水盐分异的影响,绿洲外围荒漠植被类型出现分异,从高位绿洲到中位绿洲,外围区荒漠植被的耐旱性和耐盐性均增加。  相似文献

中国生态交错带(英文)   总被引:2,自引:0,他引:2  
生态交错带(Ecotone)是指两个群落或两类生态系统之间的过度带,具有脆弱、敏感和易变等特性。20世纪70年代以来,在典型生态系统研究的基础上,生态交错带逐步成为生态学研究的重点。中国地域广阔,地质、气候、植被等生态类型复杂多变,蕴育了不同类型、不同尺度和不同规模的多种生态交错带,不仅为科学研究奠定了广阔空间,而且对我国经济、社会发展,以及文化多样性保护具有重要支撑作用。本文根据我国大尺度下生态交错带的地理分布及其生态环境特点,构建了以土地利用类型、自然气候特征和农业经济发展"三位一体"指标体系,并以此为依据对中国典型生态交错带进行了划分和空间分布范围的界定;在此基础上,分别对北方森林草原交错带、北方农牧交错带、西北荒漠绿洲交错带、西南川滇农林牧交错带和东部海陆交错带的动态变化、基本特征和存在问题进行了研究,对全面认识我国生态交错带自然演变规律,促进区域生态环境保护和优化经济发展具有重要意义。  相似文献

我国北方地区春夏季节沙尘天气频发,精准识别沙尘源区对于沙尘天气预报及区域生态环境治理意义重大。以新疆为典型研究区,采用2000、2005年和2010年3期土地利用/土地覆被数据,分析了新疆沙尘源的空间分布格局,并基于土地类型转移矩阵分析了不同类型沙尘源的转化情况。结果显示:新疆沙尘源的正、逆向转化主要跟人类活动相关。(1)沙漠/沙地转化敏感区主要分布于塔克拉玛干沙漠的西北边缘地区;转化为裸土类型沙尘源最主要的土地类型为河流/湖泊和草地,其中河流/湖泊的转化主要受自然条件影响,而草地的转化则是由过度放牧所导致。(2)岳普湖、伽师和巴楚等县区存在过度放牧现象;塔里木盆地北部以及准噶尔盆地内部等绿洲-荒漠交错带及人口聚集区域,存在大面积的垦荒现象。(3)新疆地区绿洲-荒漠交错带面积广阔,但其生态系统脆弱,为潜在的沙尘源区,应科学划定生态保护区,禁止过度放牧和无序垦荒。本文研究结果有望为区域生态环境治理及农牧业发展提供科学依据。  相似文献

中国西部生态经济走廊综合开发的战略转变   总被引:2,自引:3,他引:2  
河西走廊是一条事关国家和地区生态安全及经济安全的具有战略意义的生态经济走廊和旅游走廊,是我国西部大开发战略重点区域“两带一区”的重要组成部分,是我国西部建设的唯一一个实体型生态经济走廊。建设好这条生态经济走廊,需要实现经济综合开发的10大战略转变。即:由“古丝绸之路走廊”转变为“新欧亚大陆桥走廊”,由开发移民走廊转变为生态移民走廊,由粮食走廊转变为肉食走廊、制种走廊和草业走廊,由单一工矿走廊转变为综合型生态工业走廊,由串珠状城镇走廊转变为生态城市走廊,由缺水走廊转变为生态节水走廊,由生态脆弱走廊转变为“生态重建走廊”,由战争要道走廊转变为战略要冲走廊,由“多病的生存经济走廊”转变为“健康的生态经济走廊”。通过上述战略转变,重振丝路雄风,把河西走廊建设成科技型、节水型、外向型、加工型和生态型的健康生态经济长廊。  相似文献

以黑河中游平川绿洲和六坝绿洲为例,对绿洲及绿洲-荒漠生态过渡带土壤含水量空间分异进行了分析研究。结果表明:在无灌溉条件下绿洲及绿洲-荒漠生态过渡带的土壤含水量水平分异明显,绿洲土壤含水量高于绿洲-荒漠生态过渡带和荒漠地区土壤含水量,并出现从绿洲到绿洲-荒漠过渡带和荒漠依次递减的趋势,主要受土壤性状、土壤水分水平运动和绿洲-荒漠局地大气环流影响;绿洲活动层土壤含水量垂直分异上表现为从表层向下逐渐增加,而过渡带和荒漠区活动层土壤含水量垂直分异则是表层和底层比20~30cm处低,可能与荒漠土壤凝结水的形成与运动有关。受绿洲地下水过度开采和绿洲边缘人类活动影响,在绿洲-荒漠过渡带形成了生态裂谷,对绿洲生态系统的安全构成威胁。  相似文献

从不同生态功能区分析生态系统服务价值有助于认识生态系统服务功能的异质性。以肃南裕固族自治县、甘州区和民勤县为例,分别计算了河西走廊南部山地、中部绿洲、北部荒漠区2002年和2009年的农田生态系统服务价值,并采用多元逐步回归模型分析了不同功能区人类活动对农田生态系统服务价值变化的影响。结果表明:河西走廊单位面积农田生态系统基本服务价值和农田生态系统服务总价值都呈北部荒漠>中部绿洲>南部山地的空间梯度分异;在研究期内,不同生态功能区农田生态系统服务总价值都呈增长趋势,其中北部荒漠区增加了1.83×108元、中部绿洲增加了0.70×108元、南部山地增加了0.13×108元;农田生态系统基本服务价值,北部荒漠区年均增加0.16×108元、中部绿洲年均增加0.11×108元、南部山地年均增加0.02×108元;使用化肥等导致农田环境污染损失的价值都表现出不同程度的增大趋势;农业耗水损失价值方面,下游荒漠区年均减少0.11×108元,而中部绿洲年均增加0.03×108元,南部山地变化较小;回归分析结果显示河西走廊农田生态系统服务价值的变化主要是由种植业结构调整引起的,不同生态功能区所受影响程度具有一定差异性。  相似文献

生态功能区划是协调生态保护与经济发展的矛盾、实施区域生态系统管理的重要途径。以黑河中游为研究区,基于基础地理信息数据、自然地理数据和土地覆被数据(1986、1995、2000、2010、2011年),在生态敏感性和生态系统服务重要性分析的基础上,以最小子流域为基本单元,运用二阶聚类法进行生态功能区划;并依据主导生态系统服务对研究区进行分区管理与生态调控。得出结论:(1)黑河中游生态系统类型以荒漠、草地和农田为主,占总面积的90%;森林、水域、城镇与农村居民点零星分布,所占面积不到10%;1986-2010年,农田经历了减少-扩张-再减少的变化,但城镇与农村居民点一直呈现扩张趋势;(2)西北部生态敏感性明显高于东南部,其中极敏感区(约占24%)主要位于张掖-临泽-高台平原北侧、合黎山、祁连山山前戈壁与荒漠、肃南明花区;高度敏感区(约占58%)分布于走廊中部冲洪积平原;(3)各生态系统服务重要性空间分布格局具有一定的相似性,非常重要和极重要综合服务功能区约占3.2%,位于走廊中部的黑河干流缓冲区内;中等和一般重要地区约占20%,分布在山丹和民乐境内祁连山、焉支山、龙首山附近;(4)黑河中游可分为祁连山森林草地生态区、走廊冲洪积平原农田生态区和走廊北部平原灌丛荒漠生态区3个生态区8个生态功能区,依其主导生态系统服务分为生态保育区、生态协调区和生态控制区3类,进而提出了对应的生态系统管理措施。  相似文献

通过野外样方调查河西走廊西段荒漠戈壁典型灌木群落多样性状况,研究探讨了 8 种典型 灌木群落物种多样性的空间分布格局及其与地理因子的关系,对荒漠戈壁植物群落的多样性的保 护和可持续发展具有重要意义。结果表明:(1) 8 个典型灌木群落 Shannon-Wiener 指数、Simpson 指 数、Margalef 指数和 Pielou 指数从高到低为:盐爪爪群落>麻黄群落>合头草群落>红砂群落>梭梭群 落>泡泡刺群落>多枝柽柳群落>沙拐枣群落;波动范围分别为 0.314 ~ 1.355、0.179 ~ 0.666、0.334 ~ 1.222 和 0.051 ~ 0.218,说明荒漠戈壁灌木群落物种多样性指数偏低,群落结构简单,物种组成稀 少。(2) 不同灌木群落内物种数越多,群落间 Jaccard 相似性系数越大。大部分灌木群落类型间 Jac? card 相似性在 0.20 ~ 0.60 之间,群落间相似水平较低,群落相对稳定。(3) 随着海拔的升高,Margalef 指数、Pielou 指数和 Shannon-Wiener 指数均呈先增加后降低的单峰型分布格局,最大值出现在海拔 2 000 m,且与海拔显著相关(P<0.05);在经度梯度上,从东到西,Margalef 指数、Pielou 指数和 Shan? non-Wiener 指数呈递增格局,但与经度无显著相关性(P>0.05);在纬度梯度上,从南到北,Margalef 指数、Pielou 指数和 Shannon-Wiener 指数呈显著递增趋势(P<0.05)。总体上,荒漠戈壁灌木群落物 种多样性呈现出明显的垂直(海拔)和纬度地带性分布格局。  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

Much science-fiction literature is based upon the creation and exploration of alternative environments. Stanley G. Weinbaum's short story, “Parasite Planet,”introduces an unusual environment that may be wrong in the light of recent evidence on Venus but still stimulates the geographical imagination.  相似文献
