中文摘要：

产地损失和破碎主要与危及的种类和生物多样性损失的人口减少被联系。在 1992， 1999 和 2006 的使红圆满的鹤(Grus japonensis ) 的产地适用性地图被在黄河三角洲自然保护区使用生态的壁龛适用性模型(ENSM ) 生产(118 度 33'-119 度 20'E 经度， 37 度 35'-38 度 12'N 纬度) ，山东省，中国。基于产地适用性地图，引起和产地损失和使红圆满的鹤的破碎的变化法律被选择一系列风景模式索引分析。结果证明由于淡水来源的缺乏，在 1999 的使红圆满的鹤的产地适用性在 1992 和 2006 低于那不管人的骚乱是否存在。而且，人的骚乱活动，特别道路骚乱，在 1992-2006 的时期期间很快增加了。这变得更坏产地损失和使红圆满的鹤的破碎，并且在 2006 导致了使红圆满的鹤的降级的产地适用性，与那相比在 1992。在结论，淡水来源和人的骚乱活动是驾驶使红圆满的鹤的产地适用性变化的二个主要因素。

英文摘要：

Habitat loss and fragmentation are mainly associated with population decrease of endangered species and biodiversity loss. The habitat suitability maps of red-crowned crane （Grusjaponensis） in 1992, 1999 and 2006 were produced by using Ecological Niche Suitability Model （ENSM） in Yellow River Delta Nature Reserve （118°33′-119°20′E longitude, 37°35′-38°12′N latitude）, Shandong Province, China. Based on the habitat suitability maps, the causation and change law of habitat loss and fragmentation of red-crowned crane were analyzed by selecting a series of landscape pattern indices. Results showed that due to scarcities of fresh water sources, habitat suitability of red-crowned crane in 1999 was inferior to that in 1992 and 2006 no matter whether human disturbances existed or not. Besides, human disturbance activities, especially road disturbances, increased rapidly during the period of 1992-2006. This worsened the habitat loss and frag- mentation of red-crowned crane, and led to degrading habitat suitability of red-crowned crane in 2006, compared with that in 1992. In conclusion, fresh water sources and human disturbance activities are the two main factors that drive the habitat suitability change of red-crowned crane.
