基于3S技术的广西喀斯特石漠化驱动机制图谱分析--以广西壮族自治区为例 总被引:14,自引:0,他引:14
喀斯特石漠化是指喀斯特区地表出现类似荒漠景观的土地退化过程。图谱分析为喀斯特石漠化研究提供了一种谱系化、定量化与定位化相结合的研究方法。以广西喀斯特区为例,从组成喀斯特生态系统的地质、岩性、植被、地貌、气候及人类活动等多个方面入手,采用3S技术,得出石漠化分布及其驱动因子图;对石漠化分布图及驱动因子图进行图形叠加运算及相关分析,诊断出石漠化驱动机制。结果表明,喀斯特石漠化是在脆弱的生态环境地质背景上由于人类的强烈扰动而形成的,是多种因子综合的结果。 相似文献

基于RS和GIS的喀斯特石漠化驱动机制分析--以广西都安瑶族自治县为例 总被引:18,自引:4,他引:18
喀斯特石漠化(Karst Rocky Desertification,KRD)是指喀斯特区地表出现类似荒漠景观的土地退化过程。采用RS和GIS技术,对都安喀斯特石漠化程度分级状况与驱动因素进行全面调查,建立全县1:10万喀斯特石漠化数据库。利用相关分析、因子分析和回归分析等方法,分析导致石漠化的影响因子,即喀斯特石漠化的重要驱动力,建立了喀斯特石漠化动力指数模型,算出了各因子对石漠化的贡献值,指出石漠化产生的主导原因是不合理的人为活动。所建的动力指数模型输出结果与遥感调查有相对一致性,表明石漠化动力指数能较好地反映该地区石漠化过程,可为喀斯特石漠化治理提供理论依据。 相似文献

嘉陵江中下游地区近30年土地利用与 覆被变化过程研究 总被引:7,自引:2,他引:7
喀斯特石漠化问题是存在于喀斯特区的一种重要的地质-生态灾害。石漠化灾害的预警分析包括设计警标、明确警情、寻找警源、分析警兆和预报警度等;而石漠化灾害风险评估是在喀斯特石漠化预警分析的基础上,进行灾害危险性评价,结合易损性分析,进行期望损失评估,目的就在于评估和监测石漠化的演变状态与引起的不良环境效应。要构建一个具有操作意义的石漠化灾害预警与风险评估模型库系统,首先要建立一套合理的喀斯特石漠化灾害预警与风险评估概念化模型,据此来辩识石漠化的发育度,诊断潜势度,预警危险度,核算易损度和评估危害度。本文在于揭示脆弱的喀斯特生态环境系统的演变过程及其引起的石漠化灾害系统的成因机理与致灾过程,在此基础上,进行喀斯特生态安全预警和石漠化灾害风险分析指标体系;利用GIS技术与空间统计分析和数学模型,建立石漠化灾害风险评估模型,为我国西南喀斯特山区土地石漠化预警和灾害防治评估与不同类型石漠化区的可持续发展提供可借鉴的范例。 相似文献

石漠化景观格局对土地利用时空演变的响应 总被引:1,自引:0,他引:1
土地利用是人类活动最直接的表现形式,喀斯特地区的石漠化演化与土地利用变化有密切关系,石漠化治理是在人为干预下加快恢复脆弱的喀斯特生态系统.运用3S技术和景观格局空间分析技术相结合的手段,对石漠化综合治理下,紫云县水塘小流域的土地利用及石漠化景观格局时空演变关系进行了探讨.结果表明:1.2004-2010年间水塘小流域土地利用类型以林地及草地变化较多,其他地类变动较少,其中林地面积增加10%,草地面积增加5%;2.2004-2010年间水塘小流域石漠化变化主要类型为,中度石漠化转轻度石漠化面积5%,轻度石漠化转潜在石漠化面积10%;3.2004-2010年间水塘小流域土地利用和石漠化景观格局,多样性指数各提高了0.3和0.12,破碎度指数各减少了0.138和0.16,优势度指数各降低了0.181和0.126,均匀度指数各提高了0.092和0.209,分维度指数各提高了0.02和0.18.研究发现运用土地利用与石漠化转移矩阵与景观格局相结合的分析方法,可为评价石漠化治理成效提供借鉴意义. 相似文献

广西喀斯特山区土地石漠化与扶贫开发探析 总被引:18,自引:2,他引:16
石漠化是喀斯特脆弱生态环境和不合理人类活动的共同产物。石漠化地区人口-资源-环境的矛盾非常突出,生态恶化与贫困化的双重压力严重制约区域可持续发展。广西石漠化面积达2.93×104hm2,占石山面积的30%,且以每年1.03%的速度发展,这已经成为影响当地社会经济、资源与环境协调持续发展的关键因素。在分析广西喀斯特山区石漠化及其环境影响效应基础上,对土地石漠化的时空特征、区域环境进行了阐述,认为自然生态环境脆弱、人口素质低和外部基础条件差是广西石漠化治理的难点所在。结合广西喀斯特山区的自然、社会、经济发展实际情况,以适生适种、生态补偿、综合开发为准则,因地制宜地制定广西喀斯特山区石漠化治理与扶贫开发的模式及策略。 相似文献

黔西南脆弱喀斯特生态环境空间格局分析 总被引:54,自引:3,他引:54
西南喀斯特地区是我国四大生态脆弱带之一。黔西南具有典型的喀斯特生态环境,是西部大开发中生态环境的重点治理区。长期以来,由于人类不合理的开发利用使得喀斯特地区出现了严重的土地石漠化、土壤侵蚀以及森林生态系统退化等生态问题,制约着地区生态-经济的持续发展。本文根据已有的研究成果,在GIS技术的支持下,分析了研究区内主要生态退化问题的现状和空间格局及其影响因素,运用空间叠加分析功能,构建了生态脆弱度指标,并将研究区分为四个亚区,为生态环境治理提供科学依据。 相似文献

生态修复措施会对生物多样性热点区域产生强烈影响,因此量化石漠化治理对生物多样性的贡献在西南喀斯特地区是至关重要的。本文通过回归分析以及残差趋势分析等方法,揭示了2000—2020年中国西南喀斯特地区石漠化及生物多样性的时空演变规律,量化了石漠化治理等因素对生物多样性的贡献。结果表明:中国西南喀斯特地区石漠化以轻度石漠化和中度石漠化为主,石漠化总面积减少了10.25万km2,减少速率为0.49万km2/a;喀斯特地区生物多样性总体呈增加趋势,生物多样性综合指数均值为0.40,总体维持在中等水平;石漠化治理和生物多样性呈正相关关系,其对生物多样性的贡献为26.39%;气候变化和人类活动对生物多样性的贡献分别为52.78%、47.22%。结果表明,石漠化治理对生物多样性表现出积极贡献,对后续生态修复工程的实施以及生物多样性的保护具有一定指导意义。 相似文献

喀斯特高原峡谷与高原盆地区石漠化及变化特征对比 总被引:2,自引:0,他引:2
以贵州典型喀斯特峡谷和高原盆地区为研究对象,以5期卫星遥感影像为数据源,综合运用“3S”技术,辅以其他参考图件获得研究区不同时段石漠化图,通过对研究区石漠化状况及工程治理后动态变化特征作对比分析,探讨不同地貌类型区石漠化及其变化特征的差异性。研究表明:石漠化发生与演变和地貌类型存在一定相关性,花江喀斯特峡谷区和清镇喀斯特高原盆地区石漠化发生率分别为67.4%和31.6%,花江喀斯特峡谷区石漠化面积、石漠化发生率、石漠化强度明显地高于清镇高原盆地区。2000―2010年,花江喀斯特高原峡谷区和清镇喀斯特高原盆地区石漠化面积分别减少2.79和5.04 km2,石漠化年变化率分别为-0.91%和-2.78%,清镇喀斯特高原盆地区石漠化减少更明显。在监测时段内,花江喀斯特高原峡谷区石漠化年变化率先增加后逐渐减少,而清镇喀斯特高原盆地区则一直保持较高的石漠化年变化率,这在一定程度上说明石漠化越严重,治理越难,治理成效越不明显。当前开展的石漠化治理专项工程应根据不同地貌类型差异合理布设治理工程,先易后难,重点做好轻、中度石漠化地区的石漠化治理工作。 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
