A study of the Kazdagi (Mt. Ida) National Park: an ecological approach to the management of tourism

In the field of tourism, where environmental resources are the primary attraction, ecotourism is one of the sustainable approaches now considered as an alternative when considering today's increasing environmental problems. Indeed, according to the World Tourism Organisation, ecotourism is the fastest growing market within the tourist industry. The purpose of this study is to determine tourism activities sensitive to the environment, to help tourism in Turkey and neighbouring countries, and to help spread ecotourism by protecting biological species. The Kazdagi (Mt. Ida) area in Turkey is used as an example and case study.     

基于层次分析法的城市河流生态修复评估

城市的发展改变了许多河流的自然水文环境,并导致河流生态系统中水质、物理生境和生物完整性下降。评估受损河流水体修复的效果,需要结合物理、化学的参数,以及对生物结构、多样性和过程的影响。构建了包含河流水力、水质、水生生物、河岸带及物理结构5个方面15个指标的城市河流生态修复评估指标体系,运用群组决策的层次分析法(AHP),确定了各指标的权重,重要性排序前5位依次为：水质污染指数、鱼类IBI、水源补给量、藻类多样性、透明度。并以我国南方城市岐江河整治修复状况为例进行综合评价,结果表明,河流生态系统修复评估结果为可以接受,体现了河流整治工程使河流水质、生态的状况有所改善,但河流生态系统恢复需要较长的周期,修复初期生态系统仍处于受损状态。〖

接种不同普通活性污泥培养厌氧氨氧化污泥的研究

采用厌氧氨氧化反应器（ASBR）,分别以普通厌氧活性污泥、混合污泥、好氧活性污泥为种泥,通过对氨氮,NO2^--N等指标监测、分析及污泥颜色的观察,研究采用不同普通活性污泥为种泥启动ASBR的可行性及差异。结果表明．ASBR反应器A和B成功启动,C因反应器故障．启动失败。采用厌氧活性污泥为接种污泥（反应器A）,当进水N的容积负荷为kg／（m^3·d）时,氨氮平均去除率为14.4％。P（NO2^--N）：p（NH4^＋-N）变化量为1．24。采用混合污泥为接种污泥（反应器B）．N的容积负荷于前者相同时,氨氮去除率平均29．7％,p（NO2^--N）：p（NH4^＋-N）变化量为1．27。采用混合普通活性污泥作为种泥培养厌氧氨氧化污泥优于单一厌氧普通活性污泥。     

Production of brown and black pigments by using flotation waste from copper slag.

One of the major problems in copper-producing countries is the treatment of the large amount of copper slag or copper flotation waste generated from copper slag which contains significant amounts of heavy metals such as Cu, Zn, Pb and Co. Dumping or disposal of such large quantities of flotation waste from copper slag causes environmental and space problems. In this study, the treatment of flotation waste from copper slag by a thermal method and its use as an iron source in the production of inorganic brown and black pigments that are used in the ceramic industry were investigated. The pigments were produced by calcining different amounts of flotation waste and chromite, Cr2O3, ZnO and CoO mixtures. The pigments obtained were added to transparent ceramic glazes and porcelainized tile bodies. Their colours were defined by L*a*b* measurements with a spectrophotometer. The results showed that flotation waste from copper slag could be used as an iron source to produce brown and black pigments in both ceramic body and glazes.     

Factors affecting in vitro plant regeneration of the critically endangered Mediterranean knapweed (Centaurea tchihatcheffii Fisch et. Mey)

Habitat destruction has resulted in the extinction of many plant species from the earth, and many more face extinction. Likely, the annual endemic Mediterranean knapweed (Centaurea tchihatcheffii) growing in the Golbasi district of Ankara, Turkey is facing extinction and needs urgent conservation. Plant tissue culture, a potentially useful technique for ex situ multiplication, was used for the restoration of this ill-fated plant through seed germination, micropropagation from stem nodes, and adventitious shoot regeneration from immature zygotic embryos. The seeds were highly dormant and very difficult to germinate. No results were obtained from the micropropagation of stem nodes. However, immature zygotic embryos showed the highest adventitious shoot regeneration on Murashige and Skoog (MS) medium, containing 1 mg l⁻¹ kinetin and 0.25 mg l⁻¹ NAA. Regenerated shoots were best rooted on MS medium containing 1 mg l⁻¹ IBA and transferred to the greenhouse for flowering and seed set. As such, the present work is the first record of in vitro propagation of critically endangered C. tchihatcheffii, using immature zygotic embryos, and is a step forward towards conservation of this indigenous species.
