描述： 渭河上游和西汉水上游是中国文明的重要发源地之一。考古发掘表明,本区保存有丰富的从旧石器时代晚期至新石器时代的文化遗存。文章从历史地理学的角度,以流域和文化板块为单元,全面、系统地研究了本区原始经济形态、历史文化景观格局以及环境变化与古文化变迁之间的互动关系。 该区地处关陇交通枢纽,至迟在旧石器时代末

全文：(4200aBP-4000aBP),锄耕农业占据主导地位,土质疏松、气候温凉干燥的渭河干流以北的黄土丘陵沟壑区农业增长速度最快。4000aBP前后,气候快速向干凉发展,受强烈干旱的打击,齐家文化衰落并消失,经济形态也由农业经济向半农半牧转变。此后北方游牧文化南下,侵入本区渭河以北地区;同时文化分异加速。

杨屾农桑试验研究

作者： 刘伟   来源： 西北农林科技大学 年份： 2012 文献类型 ： 学位论文 关键词： 农学   杨屾   蚕桑   理学  

描述： 杨屾生于康乾治世、列于关学谱系，一生从事农桑试验与推广，且《清史稿》无传，《续修陕西通志》和民国重修《兴平县志》等也只着重记述他在家乡推广桑蚕及其学术上的成就，较少涉及其他方面。本文以事写人，以杨屾农桑试验为节点，力图廓清一代关中学人的思想、实践及其与社会的互动过程，勾勒清代前期一人、一地、一时之历

全文：通过教学和示范在其门生之中首先得以传播。杨氏著作广为流传，对我国北方地区的农业特别是蚕桑事业的发展起了重要作用。 总的来说，杨屾农桑试验在技术上是成功的，但他在关中地区大兴植桑养蚕的愿望却终究没有实现。究其原因，在于作为传统种植耕作区的关中已经不能适应蚕桑业的集约化、区域化的生产要求。
