| 摘 要： | 生物多样性是人类生存和发展的基础，它决定着景观生态系统的稳定性和复杂性。景观异质性是生物多样性的前提，景观异质性有利于促进景观生态系统的能量流动和物质循环，减小扰动的传播，并是生态系统生物共生的基础。干扰影响景观异质性及生物多样性，人为的干扰使景观破碎严重，直接影响生物多样性保护，自然景观的科学管理是保护生物多样性的核心与保证。

| Abstract: | Biological diversity is a basis of human's life and development. The stability and complicacy of landscape ecosystem depends on it. Landscape heterogeneity is a premise of biological diveisity. It is able to improve the energy flowing and material circulating of ecosystem, to decrease the spread of disturbance and is the basis of symbiosis. Disturbance influence landscape heterogeneity and biological diversity, especially the disturbance trom human make landscape serious broken and decrease biological diversity. Scienfific planing and managed of naturial landscape is the core and assurance of protecting biological diversity. |
