As an important aspect of ecological researches, the spatial distribution of vavious ecosystems have been studied during the last twenty years.One particularly useful application of spatial patterns analysis is to monitor the dynamic of ecosystems succession. On the other hand, it can be considered as a significant method to classify ecosystems existing in certain geographical regions. By this approach, the stability of ecosystems can be evaluated, and the primary productivity of the ecosystems can be also estimated.Considering...

As an important aspect of ecological researches, the spatial distribution of vavious ecosystems have been studied during the last twenty years.One particularly useful application of spatial patterns analysis is to monitor the dynamic of ecosystems succession. On the other hand, it can be considered as a significant method to classify ecosystems existing in certain geographical regions. By this approach, the stability of ecosystems can be evaluated, and the primary productivity of the ecosystems can be also estimated.Considering the distribution of points in a plane,the E-index(Executive Index) has been designed with the application of the nearest neighboring analysis, the gravity theory,and probability theory.In this study,the calculation of the E-index spectrum has been listed. The author has adopted the distance between two nearest neighboring quadrats containing points rather than that between two points as a conventional method to make the E-index.Some spatial adjustments and managements of ecosystems in more accurate and efficient ways can be suggested by the threshold of E-index.Applications and verification of the E-index were elucidated by some examples in this paper.

作为生态学研究的一个重要方面,在过去二十多年中,生态系统的空间分布曾被一些学者历研究。这类研究的一个特殊应用是旨在监测生态系统的动态演替。此外,它亦可以作为一种重要方法,对特定地理区域内的生态系统进行数量分类,同时,它己被用来评价生态系统的稳定性,或被用来估算生态系统的初始生产力。 考虑到一个平面上点的分布规律之后,作者应用“近邻分析”,“引力理论”以及概率论的基本概念,设计出一个称之为“执行指标”的E-index。本文列出了E-index谱的计算。其特点在于,不是如通常采用的方法那样只是考虑两点间的距离,而是采用(包含有点的)两个最近“样方”间的距离作为计算的依据,去制定执行指标, E-index似乎是在统一的基础上,在定量地比较不同的生态系境空间模型方面迈出了较大的一步,通过这个门槛,研究者们将能够以更准确和更有效的方式,去实现对生态系统的某种空间调节和空间管理。 本文还举出一些例子去应用和验证E-index。

In an ecosystem there is an interface system known as ecoboundary system existing between the biological system and physical environment system. An ecoboundary is a mediate layer consisting of a biological face on one side and a physical face on the other and functioning as a conducting system of material exchange, energy flow and information transmission under inlluenc; of forces from both sides. Such an eco-resultant force controls all mechanisms of an ecoboundary system. If the material-energy flux through the ecoboundary is thoroughly known, it could be easy to understand the fundamental relationship between organisms and environment as well as the structure and functional equilibrium of ecosystem. We take the equations of turbulent motion as a basic theoretical model for describing the thermodynamics of ecoboundary system and use the numerical differentiation method to calculate the moment flux of material-energy for continual simulation. As a result, the innate relation of organisms with environment could be directly and correctly detected. Likewise some new ideas could be developed in theoretical approaches.

在生态系统中,生物系统和非生物环境系统之间的界面称为生态界面系统。生态界面是一居间“物质薄层”。它的一侧为生物面,另一侧为非生物面,既受生物和环境的影响,又是它们之间物质交换、能量流动和信息传递的输导系统。来自生物方面的内力和来自环境方面的外力所形成的生态合力支配了生态界面系统的运动。了解生态界面系统的热力一动力学性质以及通过界面的物能流动和信息反馈特点,就可以知道生物与环境的本质关系和生态系统的结构、功能、平衡或稳定状况,从而直接评定其生态效益。本文以空气动力学中的湍流运动方程组作为求解生态界面系统的热力—动力学特性的理论依据,采用数值差分的方法,求取生态界面上瞬间变化的各种物能流动通量,不断对系统的未来状态作出模拟,又以新的模拟状态为初始态,进一步作出具有时间连续性的模拟和预测,直接而准确地反应生物与环境的本质关系和生态系统的动态特征。既避免了生态学传统方法的偏颇性,又赋予生态学新的内容。
