产地丰富影响并且甚至决定生物差异。植物产地适用性评价能为生态的恢复提供技术指导和信息支持。在地面,气象学和土壤的三个范畴的 13 个因素被选择在 Min 河的上面的活动范围造一个产地适用性评价索引框架,基于本地自然环境和植物的生长的实际影响因素。与分析层次进程(AHP ) 和熵方法结合了,它被用来计算索引的重量,产地适用性被使用一个多客观的线性 weighting 模型和地理信息系统(GIS ) 学习空间分析技术。评价结果如下:高度,土壤稳定性,方面和斜坡在 Min 河,和他们的重量的上面的活动范围在植物产地适用性上有更重要的效果分别地是 0.311, 0.260, 0.198 和 0.125。合适并且亚 suitable 产地分别地盖住 4431.80 km 2 和 6171.12 km 2, ;的大多数沿着河的双方是分布式的并且有更高的适用性。不合适产地盖住最大的区域(为 29.83% 整个区域的 6679.76 km 2), 财务;并且最糟不合适产地是 5107.23 km 2(22.81%) ;他们说明多于学习区域的一半。这些结果显示在 Min 河的上面的活动范围的植物产地是差的,生态的恢复迫切、困难。基于在生态的恢复工程采取对产地合适的措施的原则,因此,生态、工程的措施应该被联合有更好的效果,当增加生态的保护的力量时。
HabRat richness influences and even determines biological diversity. Plant habitat suitability assessment can provide technical guidance and information support for ecological restoration. Thirteen factors in three categories of terrain, meteorology and soil were chosen to build a habitat suitability assessment index framework in the Upper Reaches of the Min River, based on the local natural environment and the actual influencing factors of vegetative growth. Combined with the Analytic Hierarchy Process (AHP) and entropy method, which were used to calculate weights of indexes, habitat suitability was studied by using a multi-objective linear weighting model and geographic information systems (GIS) spatial analysis techniques. The assessment results are as follows: Altitude, soil stability, aspect and slope have more important effects on plant habitat suitability in the Upper Reaches of the Min River, and their weights are o.311, 0.260, o.198 and o.125, respectively. Suitable and sub-suitable habitats cover 4431.8o km2 and 6171.12 km2, respectively; most of which are distributed along both sides of rivers and have higher suitability. Unsuitable habitats cover the largest area (6679.76 km2), accounting for 29.83% of the whole area; and the worst unsuitable habitats are 5107.23 km2 (22.81%); they account for more than half of the study area. These results indicate that the plant habitat in the Upper Reaches of the Min River is poor and ecological restoration is both urgent and difficult. Therefore, based on the principle of taking measures suitable to the habitat in ecological restoration projects, ecological and engineering measures should be combined to have better effects, while increasing the strength of ecological protection.
