本文是对阿富汗媒体发展战略的研究,以TOLOnews TV为例,研究了媒体对阿富汗社会的影响,外国和组织援助在过去十年中在阿富汗独立媒体的兴起中所起的作用,以及当前阿富汗媒体发展所遭遇的困境和挑战。塔利班政权期间,包括电视和互联网在内的几乎所有媒体都被禁止。塔利班政权垮台后,建立先进和自由的媒体被认为是阿富汗重建的一项重大成就。阿富汗的媒体数量增加,媒体自由度大大提升。在过去的20年中,阿富汗的媒体行业发展迅速。目前,尽管有国有的报纸、广播和电视,但数十个私人和独立的电视频道和广播以及数百个私人报纸也得以快速发展,这在阿富汗历史上从未发生过。外国政府、机构和国际组织为阿富汗的媒体发展提供了大量的资助。在阿富汗,媒体被公认为为是行政、司法、立法之外的“第四种权力”。本文概述了阿富汗媒体机构的类型、发展状况和总体特征,以及阿富汗现行的媒体政策与法律。本文的主体部分是对阿富汗Tolo News TV(黎明新闻)的个案研究。通过广泛搜集黎明新闻的媒体资料,并对该媒体多个从业人员进行了深度访谈,本文分析了阿富汗媒体当前所面临的主要问题和挑战,为阿富汗媒体未来摆脱外国援助、寻求独立发展提出有针对性的对策建议。本文的研究具有一定的开创性,将有助于阿富汗传媒产业未来的发展。同时,本文对于拓展该领域的进一步研究提供有价值的个案分析。此外,本文对于研究第三世界、欠发达国家的媒体也有一定的参考和借鉴意义。

The Assessment of Carbon Stocks in the Oak Scrub Forest of Sheringal Valley Dir Kohistan

Open Journal of Forestry 2015年第5期5卷 510-517页

作者： Alamgir khan Adnan Ahmad Ziaur Rahman Siraj-ud-Din Rahmatullah Qureshi juma Muhammad Department of Forestry Shaheed Benazir Bhutto University Sheringal Dir Upper Pakistan Department of Botany University of Peshawar Peshawar Pakistan Department of Botany PMAS-Arid Agriculture University Rawalpindi Rawalpindi Pakistan Department of Environmental Sciences Shaheed Benazir Bhutto University Sheringal Dir Upper Pakistan

The present study estimates carbon stocks (C-stocks) of the Oak scrub forest of Sheringal valley through field inventory. Stem density (haǃ), tree height (m), basal area (m2·haǃ), stem volume (m2·haǃ), stem biomass (t·haǃ), total biomass (t·haǃ), and total C-stock (t·haǃ), were calculated. Stem density varied between 80±8.16 to 510 ± 42 trees haǃ, with a mean value of 226 ± 7 tress haǃ. The average tree height, basal area and stem volume were 5.47 ± 0.76 m, 12.82 ± 0.25 m2·haǃ and 46.37 ± 0.85 m3·haǃ respectively. The total calculated stem biomass was 32.46 ± 0.60 t·haǃ and total tree biomass was 51.61 ± 0.60 t·haǃ. The calculated C-stocks in the Oak scrub forest ranged from 2.005 ± 1.32 t·haǃ to 63.1 ± 3.34 t·haǃ and the mean C stocks was 25.80 ± 0.47 t·haǃ. The results of the study confirmed that the Oak scrub forest acts as a valuable sink of carbon, but this valuable storage factory of carbon faced the problems of excess uses for fuel wood, forage, domestic uses (mostly for construction) and unscientific management. Proper scientific management and proper utilization of the forest can be significant measures to enhance the potential of the forest to stored and sink more carbon and can be included for CDM and REED++ under Keyto protocol.

Journal of Geoscience and Environment Protection 2022年第4期10卷 127-144页

Aggregate is a worldwide raw material used for various construction purposes which are obtained from geological material through drilling, blasting, mining, and river derived. This study has been focused on river Panjkora and Kunai-derived aggregates which are natural sources of aggregate used for various construction purposes in Dir (Lower). Field observation and detailed petrographic studies of representative samples reveal that rivers Panjkora and Kunai pass from different lithological units of granite, gabbroic, and amphibolite. Petrographically, the granitic rocks of the study area are consisting of alkali feldspar, quartz, and plagioclase feldspar. Minor accessory minerals in granite were hornblende, biotite, epidote, rutile, zircon, and ore minerals. The gabbroic rocks are consisting of pyroxene, plagioclase, and minor to accessory minerals including biotite, sphene, rutile, epidote, and ore minerals. The main mineral phases in amphibolites are hornblende, plagioclase, and a minor amount of quartz, sphene, and ore minerals. Gneissose fabric has developed in amphibolite refers to its banded nature. The minor mineral phases of amphibolite include epidote, ore minerals, and garnet. The feldspar alteration in granite is in the form of sericitization and normal zoning. The physical properties of river Panjkora and Kunai float i.e., water absorption, specific gravity, fine modulus, loss Angeles and soundness were within the range. Both petrographic and geotechnical properties suggested that these aggregates are suitable to be used as coarse aggregate in concrete. These must be present in the recommendation section at the end.
