| 1 | 华南丘陵区村级景观下土地利用/土地覆盖对土壤质量的影响显示文摘利用IKONOS高分辨率(1m)卫星遥感图,根据Ellis提出的村级景观分类体系,研究华南丘陵区村级景观中的土壤容重、土壤有机质、土壤全氮和土壤全磷的含量和分布特征。结果表明:不同土地利用景观中,表层土壤(0~15cm)的土壤容重、有机质和全氮均有显著差异,最大值分别为:1.42gcm^-3(建设用地)、18.67g kg^-1(水田)和0.95g kg^-1(水田),而全磷差异不显著。由于林地面积最大,其土壤养分储量也最大,表层土壤有机质、全氮、全磷储量分别占整个地区表层总储量的55.05%、53.88%、46.23%。不同土地覆盖景观中,表层土壤的土壤容重、有机质、全氮也都有显著差异,最大值分别为:1.42gcm^-3(硬化地面)、15.96g kg^-1(混合植被)和0.68g kg^-1(混合植被),而全磷差异也不显著。多年生植被在土地覆盖景观中所占面积最大,其表层土壤有机质、全氮、全磷储量分别占整个地区表层总储量的55.01%、54.53%、59.02%。由于下层受人为干扰较小,不论是在不同土地利用方式还是在土地覆盖下,下层土壤(15~30cm)的土壤容重、有机质、全氮和全磷均无显著差异。人为强烈干扰下,植被覆盖度低的交通用地、房屋及其附近的干扰地和荒地与植被覆盖度高的林地、水田相比较,土壤容重高,而土壤有机质、土壤全氮和土壤全磷含量低。 | 焦加国 武俊喜 李辉信 杨林章 肖红生 Erle C Ellis | 2007 | 土壤学报2007,44,2: | 13 |
| 2 | 1940-2002年长江中下游平原乡村景观区域中耕地类型及其土壤氮磷储量的变化显示文摘过去60a间,长江中下游平原乡村景观区域中土地利用覆被类型,特别是耕地类型发生了显著地转变,并对其土壤全氮和全磷产生了明显地影响。通过选取区域代表性样方、研究耕地类型的小尺度转化、土壤取样和收集1965年前土壤全氮、全磷历史数据,采用尺度推绎和蒙特卡洛不确定性分析方法,评价了1940-2002年长江中下游平原人口密集的乡村景观区域中耕地类型及其土壤全氮、全磷储量的变化。结果表明:近60a来,在86×103km2的区域中有47%的面积发生了变化,其中33%的面积是耕地类型转化。耕地面积减少18.6%(-16.0×103km2),其中稻田面积减少21.5%(-18.5×103km2),种植木本作物的旱地面积减少1.7%(-1.5×103km2);而种植木本作物和种植1年生作物的水浇地的面积分别增加了3.5%(3.0×103km2)和2.0%(1.7×103km2)。尽管稻田面积大幅减少,但其仍是区域中面积最大的土地利用覆被类型。1940-2002年,有98%的可能性区域耕地0-30cm土壤全氮储量净减少,而其0-30cm土壤全磷储量则无明显变化。区域耕地土壤全氮储量明显减少(-7.2Tg N),主要受稻田土壤全氮储量显著减少(-8.0Tg N)的影响,而稻田面积大幅减少是导致稻田土壤全氮储量减少的主要原因。与此同时,种植木本作物的旱地的土壤全氮储量减少了0.7Tg N;而种植木本作物和种植1年生作物的水浇地分别增加1.3和0.7Tg N。区域耕地土壤全磷储量变化不明显,主要受稻田土壤全磷储量无明显变化的影响。尽管稻田面积大幅减少,但由于稻田土壤全磷密度增加了29%(其净增加的可能性为76%);加之稻田土壤全磷密度变异较大,所以稻田土壤全磷储量并没有明显减少,其净减少的可能性仅为64%。与此同时,有75%的可能性种植木本作物的旱地的土壤全磷储量净减少,但仅减少了0.3Tg P;而种植木本作物的水浇地和种植1年生作物的水浇地土壤全磷都有少量增加,分别为0.7和0.4Tg P。通过选取区域代表性样方、研究耕地类型的小尺度转化、土壤取样和收集土壤历史数据、结合尺度推绎和蒙特卡洛不确定性分析方法,能够揭示1940-2002年长江中下游平原人口密集的乡村景观区域中耕地类型及其土壤全氮和全磷储量的变化。 | 武俊喜 程序 焦加国 肖红生 杨林章 王洪庆 张福锁 Ellis Erle C | 2010 | 生态学报2010,30,23: | 4 |
