基于遥感技术的三峡库区土壤侵蚀量评估及影响因子分析

基于遥感和地理信息系统技术,利用修正通用土壤流失方程对三峡库区的土壤侵蚀进行定量评估,并进一步分别利用MODIS、TRMM遥感数据对其变化影响的主要因子植被覆盖和降雨侵蚀力变化进行了分析.结果表明:2005年土壤侵蚀总量为11 979.19×104t,平均土壤侵蚀模数为2 087 t/(km2·a),与2000年土壤侵蚀模数2 381 t/(km2·a)相比,减少了294 t/(km2·a).库区东部长江两岸大部分地区植被出现增长趋势,位于研究区边缘附近植被变化不明显;库区降雨侵蚀力总体呈增加趋势,同时降雨侵蚀力年际变化存在较明显的空间差异性.     

基于RS的岷江流域土壤侵蚀变化及其驱动力分析

依据1995年、2000年土壤侵蚀遥感数据并结合2005年实地调查资料,研究岷江流域土壤侵蚀演变规律及其驱动力。研究结果表明:1)2000年岷江流域土壤侵蚀面积为19 907.7 km2(比1995年减少369.6 km2),占流域面积的43.77%,土壤侵蚀量为8 943.26万t,平均侵蚀模数1 966 t/(km2.a),以水蚀和中度侵蚀为主。2)选择降雨变化、土地利用变化、植被覆盖度变化3个自然因素和人口密度、万元GDP(作为经济发展指标)2个社会发展指标作为研究区土壤侵蚀变化的驱动因素。结果表明:2000年降雨侵蚀力对土壤侵蚀的影响是1995年的71%;森林覆盖率每增加1%,土壤侵蚀模数减少0.4%~7%,平均减少53 t/(km2.a);林地、草地面积之和与土壤侵蚀面积呈明显的线性相关,旱地面积与土壤侵蚀面积呈二次函数关系;土壤侵蚀面积、土壤侵蚀量与万元GDP呈指数关系;单位人口密度和县域土壤侵蚀面积与土壤侵蚀量均呈幂指数关系。     

基于TETIS模型的黑土区乌裕尔河流域径流与侵蚀产沙模拟研究

为科学地认识中国东北黑土区流域土壤侵蚀特征,探讨TETIS模型在该区的适用性,本文以乌裕尔河流域为例,利用1971-1987年日径流与泥沙实测数据对TETIS模型进行了校正与验证,进而分析了流域土壤侵蚀强度特征及其与坡度、土地利用方式的关系。研究结果表明：TETIS模型在乌裕尔河流域适用性好,日径流与日输沙量的纳什效率系数在0.52~0.70之间,决定系数在0.60~0.71之间,体积误差均不超过15%。流域平均侵蚀模数为397.2 t/(km²·a),流域以微度和轻度侵蚀为主,约90%的产沙来自于坡面。平均土壤侵蚀模数随坡度的增大而增大,流域侵蚀量主要来自于0°~5°坡面。不同土地利用方式具不同的土壤侵蚀模数,耕地土壤侵蚀模数最大,达556.3 t/(km²·a)。坡度较大的耕地和植被覆盖度较低的区域是水土流失治理的重点。研究表明,TETIS模型在黑土区模拟土壤侵蚀产沙应用前景好,可为研究区制定水土保持措施提供科学依据。     

137Cs示踪技术在黑土区农业非点源污染负荷研究中的应用

利用¹³⁷Cs核素示踪和定位监测相结合,研究松嫩平原黑土区3个旱作坡面土壤的流失厚度和流失速率,坡面土壤流失厚度1.20~5.25 mm/a,侵蚀强度1 355.0~7 558.2 t/(km²·a);近40 a来,松嫩平原黑土区年均入河(湖)农业非点源污染负荷分别为TN 1.43 t/(km²·a)、NH₃^-N 15.01 kg/(km²·a)、NO₃^-N 8.51 kg/(km²·a)TP 0.42 t/(km²·a)、PO₄^3--P 1.85 kg/(km²·a);土壤流失氮以有机氮为主;水溶态无机氮占总氮的0.51%,水溶性磷酸盐磷占总磷的0.12%。黑土区农业非点源污染物的输出和水土流失密切相关,深入研究其输移机理及防治措施具有重要的环境意义。

运用1 37Cs示踪法对长江上游“长治”水土保持工程重点治理区的云贵高原区、川中丘陵区和三峡库区 8块紫色土坡耕地土壤侵蚀速率研究结果表明 ,影响紫色土坡耕地平均侵蚀速率的主要因子为坡度、坡长、降雨量和土壤粒度组成 ,四个研究区土壤平均侵蚀速率介于 75 8t km2 ·a- 1 ～ 985 4t km2 ·a- 1 ,计算值与长江上游类似地区径流试验场观测值基本一致。     

基于GIS的小流域土壤侵蚀与产沙的简化模拟

将泥沙输移能力公式与USLE公式相结合,建立了一个简化的分布式小流域产沙模型,并将其应用于川中丘陵区小流域的土壤侵蚀与泥沙输移的空间分布模拟。得到的主要结论:1.该模型适用于川中丘陵区小流域产沙的模拟;2.魏城河流域1980—1987年8 a平均土壤侵蚀量为16.8×104t,侵蚀模数为675.8 t/(km2.a),模拟得到的输沙模数为238.6 t/(km2.a),泥沙输移比为0.35;3.魏城河流域主要以微度侵蚀为主,占到全流域总面积的68%,强度侵蚀占流域面积的1%,主要分布在坡度较陡的流域边缘地带;4.相对其他因子,降雨与坡度对该流域侵蚀产沙的影响更为突出。     

陕北典型地区乡村聚落水蚀泥沙规律的初步研究

通过定位观测资料的分析,发现陕北多沙粗沙区乡村聚落的平均年侵蚀强度达5434.3t/km2,户间道路、户间空地、庭院的平均侵蚀强度分别达7348t/km2.6873.2 t/km2,2081.7t/km2.除庭院属轻度级侵蚀外,其它已达强度级侵蚀.同时延安的户间道路(14190.8t/km2),榆林的户间空地(13547.4t/km2),已达极强度侵蚀.应加强研究和防治.水蚀泥沙的粒度以0.01～0.05 mm的粗粉沙和0.001～0.005 mm的粘粒为主,分别占到43.98%和19.81%,≥0.05mm的粗泥沙含量明显小于聚落以外的坡面,而且区域变化比较明显,从南到北,细粒成分愈来愈少,粗粒成分越来越多;与土壤粒度相比,粗泥沙水蚀系数在庭院、户间道路、户间空地分别达到0.54,0.55,0.75,平均为0.61.     

137Cs示踪法研究青藏高原草甸土的土壤侵蚀

运用137Cs示踪法对青藏高原高寒草甸典型的两个小流域的土壤侵蚀进行了研究,结果表明:高寒草甸植被区的土壤137Cs在土壤剖面中呈指数型分布,分布深度一般在20cm左右;坡顶部由于风蚀、冻融侵蚀和水蚀较强,致使侵蚀强于下部,除坡顶部外其他坡位侵蚀强度都符合坡上部<坡中部<坡下部的规律;高寒草甸植被覆盖度与土壤侵蚀强度呈显著的负相关关系(p<0.01),土壤平均侵蚀模数随植被覆盖度的增加呈线性降低的趋势,相关系数R2达到0.997以上。高寒草甸退化程度越高,土壤侵蚀越强。退化较强的草甸区的平均侵蚀模数是退化较弱区的2.23倍,最大侵蚀模数可达2960.22t/(km2.a)。     

山东荣成月湖潮汐汊道系统的沉积物平衡问题——兼论人类活动的影响

在月湖进行了沉积物采样和潮汐水文观测,分析计算了表层沉积物类型、泥沙输运率、现代沉积速率,讨论了月湖的沉积物平衡。结果显示,月湖的沉积速率较快。按目前的数据和资料估算,月湖每年的沉积通量约为(1.8~2.3)×10⁴ t,而正常情况下的沉积物供应量每年只有(0.5~1.2)×10⁴ t。研究表明,人类活动还改变了月湖的物理与生态过程。由于土地利用的方式及其强度发生了变化,月湖汇水盆地的侵蚀量大为增加,侵蚀模数可能远大于400 t/(km²·a),从而使流域侵蚀量大大超出了正常范围,加剧了月湖的淤积。     

基于SWAT模型的大伙房水库汇水区农业非点源污染空间特性研究

应用SWAT模型对辽宁省大伙房水库汇水区农业非点源污染进行了模拟,利用2006~2009年的水文和水质监测数据对模型进行率定与验证。研究结果表明:研究区泥沙坡面产量为15.40×104t,属于微度侵蚀,其中耕地的土壤侵蚀模数最高,为475.84 t/(km2.a),疏林地次之,灌林地、有林地的土壤侵蚀模数较小;汇水区农业非点源氮、磷产生量分别为1 248.83 t和102.88 t;不同土地利用类型氮、磷的产生量差异较大,耕地远远高于林地等其他类型。总体上,流域农业非点源污染的产生量浑河流域高于苏子河流域,社河流域最小,且河流上游地区高于下游。研究结果揭示了研究区农业非点源污染空间分布特性,可以为水土保持和非点源污染防治提供基础支持。

Deserts and Aeolian Desertification in China: Book review and some thoughts

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.
