| 摘 要： | 黑土生态系统脆弱性成因自然因素和人为因素共同作用的结果；自然因素是水土流失发生发展的潜在条件，人为因素对水土流失的发生发展起了促进和加速作用；遵循生物种群与环境相适应原则，对不同地貌类型导致生物生态分异，生物种群必须与地貌格局相一致；将黑土脆弱区分为3个生态系统进行生态修复。

| Abstract: | The cause of black soil ecological system frangibility was interacted by natural and artificial factors. Natural factor was the potential condition of the occurring and developing of soil erosion, and artificial factor accelerated the black soil erosion. The repair of black soil ecological system must be divided by three frangible subareas according to the fundamental that populations must be suitable to their environment and keep coherence to the landscape. |
