It is designed to further the interchange of knowledge and ideas between specialists on different subjects, ranging from the sue of biochemical techniques in herpetological research to electron microscopy, from amphibian and reptilian genetics to the fossil history of the modern amphibians, including systematics and taxonomy as well as behaviour, physiology and ecology.

该杂志的目标是为了使从事不同研究的专家能够交换知识和想法，其内容涉及爬行类研究中从分子技术到电子显微结构水平、从两栖类遗传学到现代爬行类的化石研究的各个方面，同时包括爬行类的系统学、分类学，以及行为学、生理学和生态学等。

This study was organized in three parts. Part One: The ecological study on the relationship between environmental organochloride pollution and the incidence rate of colorectal cancer. In this part, the incidence rate of colorectal cancer was determined from the tumor registry system of Jiashan County, a highest incidence area of colorectal cancer. The soil and rice samples were collected according to the incidence rate of colorectal cancer and the geographic position of the east, west, south, north and center. The concentrations of dichlorodiphenyltrichloroethane, hexachlorocyclohexane, polychlorinated biphenyl and sodium pentachlorophenate were detected in laboratory.

共分三个部分：第一部分环境有机氯污染与结直肠癌发病率关系的生态学研究利用结直肠癌高发区嘉善县肿瘤登记报告系统，确定各乡镇结直肠癌各年度发病率；按各乡镇结直肠癌发病率的高、中低及地理位置东、西、南、北、中等结合采集土壤和大米样品，检测其DDT、HCH、PCBs及Na-PCP的含量；对这些有机氯污染指标值与相应的结直肠癌发病率之间作相关分析等统计学处理。

Behaviour ecology, physio-ecology and community ecology of vines in the evergreen broad-leaved forest of Tiantong National Forest Park, Zhejiang Province, China, were studied and rich first-hand data were collected in this project.Some vines with different climbing motheds were much different in leaf anatomy, ecophysiology, growth rhythm and behavior, and another vines with same climbing methods showed similar adaptation to habitat, on which their distribution in a forest depended. The concept of climbing unit consisted of internode, leaves and tendrils or other climbing organs on it was put forth, and the method to calculate and value the climbing capaity of a vine was set up. In the meantime,experimental ecology of a twining vine Humulus scandens was carried out.

本项目以浙江天童常绿阔叶林为基地，从行为生态、生理生态和群落生态学等角度较系统深入地研究了常绿阔叶林藤本植物的生态适应特征，取得了丰富的第一手资料，结果表明不同攀援类型的藤本在形态结构、生理生态、生长和攀援行为上表现出明显的差异，而同一攀援类型的藤本表现出较大的趋同适应的特征，但也存在着差异，这些特征或差异决定了它们在群落中分布的层次和与支持木之间的作用方式；提出了攀援单位的概念，初步建立了攀援能力的测定和评估方法。

Therefore it is required for a wide variety of climate, hydrologic, ecological and biogeochemical studies.

The progress of using new hyperspatial and hyperspectral data for directly retrieval biodiversity indexes and its limitations are discussed in this paper.

最后，总结了该方法在我国的应用局限，指出增进学科合作、将遥感方法与生态学理论和模型相结合、重视地面验证数据的使用将是生物多样性遥感研究的发展趋势。

Niche which many ecologists have become interested in is an important concept in ecology. The main definitions of niche are the habitat niche of Grinnell (1917), the functional niche of Elton (1933) and the hypervolume niche of Hutchinson (1957) whose concept has by far the largest influence on niche.

生态位是生态学的一个重要概念，许多生态学家都对生态位下了定义，主要有Grinnell(1917)的生境生态位，Elton(1933)的功能生态位，Hutchinson(1957)的超体积生态位，尤以Hutchinson的&超体积生态位&影响为大。

Based on landscape representation models, process models and evaluation models, the author discussed five design approaches to landscapes: The Feng-shui approach, Lynch's approach of "Imageable city", the "Genius loci" approach, McHarg's "Design with nature" approach and the approach of landscape ecology.

本文从景观设计过程的陈述模型，过程模型和评价模型三个方面系统讨论和比较了五个不同景观设计途径，包括前科学途径，现象学途径（包括林奇的&城市印象&途径和&场所精神&途径），以及生态学途径(包括&设计遵从自然&途径和景观生态途径)。
