The journal established in 1991, focuses on the field of macroecology: the study of broad, consistent patterns in the ecological characteristics of organisms and ecosystems, including studies addressing general ecological hypotheses, exploring and testing using data of broad geographic, taxonomic, or temporal scope; studies documenting ecological and biogeographic patterns, theoretical studies exploring the causes of those patterns, applied studies of impacts of anthropogenic influences, as well as methodological studies of the tools used to study these problems; broad-scale patterns of biodiversity, ecosystem responses to global climate change, historical and evolutionary biogeography, remote sensing of ecosystem properties, species abundance and species range patters, and statistical methodologies.

杂志创刊于1991年，主要致力于大生态学：生物体的生态学特征和生态系统广泛一致的研究，包括介绍普通生态学假设，通过地理学，分类学，或有限范围内的数据探索和试验的研究；验证生态学和生物地理学模式的研究，探索这些模式原因的理论研究，人为影响的应用研究，以及用于研究这些问题的工具的方法学研究；大尺度生物多样性模式的研究，生态系统对全球气候变化的反应，历史和进化生物地理学，生态系统的遥测，物种的丰度和物种变化模式，以及统计学方法论。

The achievement of this project can be briefly summed up as following:(1)the carbon contributing to karst processes mainly comes from ecological system itself under the condition of existence of vegetation and soil covers;(2)results indicates that the depositing processes of rainfall to CO2 is an important "sink" to global carbon cycle;(3)owing to the differences of vegetation and surface covering, the adjusting effect of ecosystem to environmental humidity, temperature and CO2 concentration near surface air which indicates different benefit of preventing water and soil from lose is marked;(4)the preponderant species of vegetation in the karst ecosystems which have different kinds of carbonate rocks are obviously variant, and this situation results to the clearly differences of the micro － habitat , structure of surface cover and water holding capacity;(5) the relevant study showed that the carpophagous animals and birds make a important role in the spreading of vegetation seeds. The designed experience for the study of seed reservoir was not able to obtain a satisfactory result.

主要研究成果包括：通过对表层系统碳库的研究，认为在有土壤和植被覆盖时，岩溶作用过程中的碳主要来自生态系统本身而不是母岩；降雨对大气碳具有重要&沉淀&作用，是碳的一个重要汇；不同植被类型表层岩溶系统对系统水份、空气湿度、气温、土温和近地表 CO2浓度等具有明显调节作用，具有不同的水土保持效益；不同母岩的岩溶生态系统的植被优势种、属差异明显，由此形成的小生境、地被物及其持水性差异巨大；对典型岩溶表层系统种子库的试验研究没有取得满意结果，但食果动物、鸟类对种子传播起到一定作用。
