孟加拉涝原地区村林居住的宗教社团偏爱的乔木和灌木树种及使用的造林材料研究     

Md.DaneshMiah MohammadMoshiurRahman 《林业研究》2004,15(1):55-60

2002年1月至6月对孟加拉涝原地区两个不同的宗教部落(印度教和穆斯林教)的传统家园森林进行了探索性研究，包括印度教和穆斯林教社团对树种(乔木和灌木)的偏爱度、类似性、造林材料及来源、植树地点和间距。研究发现Mangifera indica作为乔木树种，Ocimum sanctum作为灌木树种为印度教社团最喜爱的树种；Artocarpus heterophyllus和Lawsonia inermis分别为穆斯林社团最喜爱乔木树种和灌木树种。两中不同宗教社团选择乔木数种的相同性为86．57％，灌木树种为78．48％。两个宗教部落使用种子和苗木作为造林材料最多。乔木树种的造林材料主要来自家园(39％)灌木树种主要来自自然界(40％)。表3参27。  相似文献   

从《摩奴法典》看古印度的种姓制度     

李亦钊 《信阳农业高等专科学校学报》2013,23(2):15-17

《摩奴法典》是印度最古老的宗教、哲学与法律的汇编,由婆罗门教僧侣根据吠陀经典和历来的习惯编制而成,维护种姓制度是法典的核心内容。随着印度教的发展,种姓制度涵盖和渗透了印度社会人与人之间在政治、经济、社会生活等各方面的相互关系,在印度国内外产生了重要影响,一直持续到今天,要想消除它任重而道远。  相似文献   

Potential impacts of non‐native fish on the threatened mahseer (Tor) species of the Indian Himalayan biodiversity hot spot

1. Mahseer (Tor) fish species are critical components of locally adapted freshwater food webs across the Indian Himalayan biodiversity hotspot; however, multiple human stressors compounded by climate change have significantly depleted their populations over recent decades.
2. Mahseer species are now considered locally vulnerable or endangered in many regions. Hydropower projects in particular have fragmented populations, impairing genetic exchange, obstructing migratory paths, and changing the structure and functioning of riverine habitats, especially of formerly fast‐flowing rivers.
3. Worryingly, a literature survey and group discussions reveal that the increasing spread of non‐native fish species further compounds threats to mahseer and overall freshwater ecology. A better understanding of the current distribution, habitat requirement, and dispersal of non‐native fish is therefore essential to manage the growing threats to mahseer in the Indian Himalayan region.
