术语“灰化红壤”的详细信息

英译术语:

podzolized red earth

汉语语境:

清代整个滇池东南缘区域内的人口发展历经了低谷、峰值和回落三个阶段，由于人口与聚落、土地开垦有着密切的联系，因此清代嘉道年间的人口峰值带来了该范围内的聚落剧增和大量土地开辟。人口和聚落的发展在该区域内部也存在差异，东部的呈贡县自清初康熙年间就已奠定了整个县的聚落分布基础，乾隆至清末的聚落增加并不明显。呈贡县，降雨量呈现出由中部向南北两端逐渐增加的趋势，对于滇池东部地区的土地利用、人口分布是一个重要的影响因素。 滇池东部的土壤共有红壤、水稻土、紫色土、棕壤、冲积土五大类。 其中，红壤在呈贡县土壤中所占比重最大，主要分布于丘陵地区。根据具体地形，红壤在此区域内又分为两种，在坡度相较平缓的红土层上，多为灰化红壤及老红壤，所受淋溶及侵蚀作用较小，肥力仍较高，但土壤中碎石较多，不利于土壤的保水性。

英语语境:

The population development in the southeast of Dianchi Lake in Qing Dynasty fell back after the trough and the peak. Since the population development was closely related to settlement and land reclamation, the population peak during Jiajing and Daoguang's reigns brought rapid increase in settlement and large amount of land reclamation. There existed differences in the development of population and settlement within the region. The eastern Chenggong county had laid the foundation of settlement distribution of the whole county from Kangxi's reign in the early Qing Dynasty while the increase in settlement from Qianlong's reign to the end of Qing Dynasty was not obvious. The rainfall in Chenggong County increased gradually from the central part to the north and south ends, which was an important factor for the land utilization and population distribution in the east of Dianchi Lake. The soil in the eastern Dianchi Lake can be classified into five major categories: red earth, paddy soil, purple soil, brown soil, and alluvial soil. Among them, the red earth accounts for the largest proportion, which mainly distributes in the hilly area. According to specific terrain, the red earth in this area can be further divided into two types. The red earth layer with a relatively gentle slope was mostly podzolized red earth and old red earth, which were still with high fertility since they suffer less from eluviation and erosion. However, there was a lot of gravel in the soil, which was not good for its water-holding capacity.
