Shuitu Baochi Xuebao, 2005 通过对不同留茬高度对地表风速的影响以及留残茬(保护性耕作主要方式)、旋耕和常规翻耕3种耕作方式对土壤风蚀的影响进行比较研究,得出如下结果:留茬高度对地表风速的影响程度不明显,仅与地面有无留茬有关,留茬20cm左右即可有效降低地表风速,减少田间扬沙,抵抗土壤风蚀,是比较适宜的留茬高度;留茬(保护性耕作)、旋耕和常规翻耕3种耕作方式对田间扬沙情况的影响差异明显,其中在60cm高度以内,留茬比常规翻耕减少田间扬沙量34.9%,比旋耕方式减少61.5%,因此,留茬(保护性耕作 ...

基诺族是游耕民族而非游居民族——与周新文、陶联明同志商榷 [PDF]
, 1999 在人类学、民族学的文献中，刀耕火种也称游耕、山田烧垦、初耕农业、园艺式农业、降雨农业等。游耕是刀耕火种的一种指称，它强调的只是耕地变动性较大这一特征，而与游居无必然联系。周新文、陶联明同志既然承认基诺族过去从事的是刀耕火种的农业生产活动，那么就无法否认基诺族是从事游耕农业的事实。因此，基诺族是游耕民族的说法并没有错。但是，游耕并非游居，把基诺族视为游居民族则不妥，应该说解放前的基诺族是游耕民族而不是游居民族。 【英文摘要】 In anthropological and ethnological ...
