海南岛东南海岸带植被景观分类系统探讨

将Forman和Godron提出的基于植被(或土地利用)的景观分类方法与中国特有的土地类型分类方法相结合,采用区域性原则,综合性与主导因素相结合原则,人类干扰原则与层次性原则等分类原则,确立研究区海岸带植被景观类型系统。根据景观土地属性分类的植被分类途径,将海南岛东南海岸带景观分为植被景观、农田景观、湿地景观、建筑景观与其他景观等5种一级景观类型;针叶林、阔叶林、人工林、灌草丛和红树林等5种二级植被景观类型;青梅Vitica mangachapoi-柄果木Mischocarpus sundaicus林、榕树Ficus microcarpa-桄榔Arenga pinnata林等39种植被斑块类型(三级景观类型)。

南京幕燕风景名胜区景观生态评价与规划

风景名胜区景观生态评价可以为风景区规划、建设和管理提供重要的依据,也是实现风景区可持续发展的有效途径之一。以南京幕燕风景名胜区为例,对幕燕风景区的景观生态评价与规划进行了研究。在大量野外工作的基础上,建立了幕燕风景区次生植被分类系统,并以植被为标志,拟建了风景区景观生态分类系统,调绘了风景区景观生态现状图;选取多样性、代表性等 8项指标对风景区的景观生态进行了评价,并根据景观综合评价指数将类景观类型划分出 4个等级;以景观生态评价结果为依据,提出了风景区景观生态规划的关键措施,研制了风景区景观生态规划图;最后,根据景观生态学原理和方法,进一步提出了风景区可持续发展的建议。

Classification system and structure analysis of marine cultural landscapes of China

Marine cultural landscapes are an important part of cultural landscapes,as a new kind of heritage.With reference to the classification of cultural landscapes,a three-level classification system,composed of the marine cultural landscape type,the marine cultural landscape subtype and the marine cultural landscape model was constructed in this study,based on the spatial and regional characteristics of marine history and culture.By the analysis of the effects of natural and humanity factors on the formation of marine cultural landscapes,the system structure of the marine cultural landscapes was divided into three major parts:the physical foundation,the marked material and the recessive material.

Estimation of Antropogenenic Pressure on Landscapes of Oasises （on Example of Mid and Lower Part of Zarafshan River）

The paper discusses about anthropogenic pressure classification system on landscape oasises. As a result, based on designed criteria rates a thematic map titled ＂Anthropogenic pressure and its consequences on landscapes oasises of mid and lower part of Zarafshan River Basin＂ was developed. The thematic map depicts realthionship between ecological conditions and population diseases along various landscape oasises of the Zarafshan river valley.
