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。

Database time types and the relationship between database time and bitemporal database has been discussed. Combining the space and time, the notion of spatio-temporal model was educed.

The temporal middleware does not support the index of bitemporal data, which include the transaction time and valid time. By using the proper data transformation and query transformation, the bitemporal data can be transferred to the data of 4R index.

摘要当前的时态数据库中间件不支持包含事务时间和有效时间的双时态数据索引，通过使用适当的数据变换和查询变换，可将双时态数据转化为R树可索引的数据。

Firstly, working on the data model of temporal-relation, a bitemporal data model on object-relation is proposed in this paper, which may be implemented in current object-relational databases.

首先在现有时态关系数据模型基础上，提出了一种基于对象关系双时态数据模型，而这种数据模型适合于在现有数据库平台上实现；其次，在该模型框架内，讨论了时态对象关系模式与时态关系模式相互间的联系与转换，这也是由时态关系扩充到对象关系的基本要求：再次，分析了时态模型中时态变量复杂语义和相应绑定算法，这是时态数据库能够有效运行的基本课题
