- 摘要:
- 干旱区贫瘠土壤和植被单一是立地质量的重要指标，在水平结构上表现为一种有、无植被及不同种群组成的镶嵌分布，镶嵌分布具有的不均匀性在尺度变换下具有不变性特征；立地质量决定了抵抗破坏力度和恢复力度均弱，因而原生植被破坏时残存的幼苗或幼树经长期恢复形成了顶级单优结构。这就为应用生态学最著名的种群模型来研究其动力学行为奠定了基础。对动力学模型中的控制参数利用多种调控因子的组合分析，定量化地进行了受控变化研究，通过深入调试各种调控因子的数值范围、最佳指标的数值域和危险指标的数值域后，可提供便于操作的具体数据范围。
- Abstract:
- The poor soil and single vegetation in arid area are important indexes of site quality,which is revealed through the patchiness of the vegetated portions of landscapes and of distribution of different population in level structure.Heterogeneity of patchiness is unchangeable in scale transition.The ability of anti-destruction and restoring is feeble according to the site quality.Therefore the young tree and young seedling survived in the destruction of primitive vegetation restore to climax with a single dominant species through a long time.So it provides research basis on dynamics behavior by using the most famous population model in ecology.Control factors in the dynamics model are analyzed comprehensively by using various control factors,and the controlled changes are studied by quantitative means.After debugging the value scope of various controlling factors,the best index and the dangerous index,it provides actual value scope which is operable easily.
