3) farmland loss 耕地损失 1. Land use data of 1991,1997,2000,and 2004 obtained by remote sensing image were employed to calculate the farmland loss. 研究方法:以北京为例,在遥感影像生成的1991、1997、2000和2004年4期土地利用数据支持下分析了耕地损失特征;利用气象数据结合桑斯维特纪念模型计算了...
regional scales. The advantage of using the local experimental data is that by strictly controlling for species richness, composition, and other confounding factors, local experiments can disentangle the causal effects of species richness on biomass production. This assumes that (1) local loss of spec...
Bareland and farmland have been expanding at the expense of other land use types. The annual soil loss in the watershed ranged from 0 to 113.21 t ha−1year−1, 0 to 163.16 t ha−1year−1, and 0 to 194.58tha−1year−1with a mean annual soil loss of 21.07, 29.35 and 4...
For instance, in the highlands of Ethiopia yearly productive capacity is falling by 2.2% year−1 (Tesfahunegn et al. 2014). In the last four decades, many researchers developed and used soil erosion assessment models using geospatial technologies to quantify soil losses (e.g., Wischmeier ...
"Ecologically-based agriculture is highly productive, and this approach can complement traditional types of conservation. "We need to make a rapid transition from green agricultural deserts to verdant oases that combine economic productivity with movement and habitat of species affected byclimatechange. ...
