稀有生境日益受到破碎化的威胁，需要采取措施保护这些宝贵的资源。在这里，我们提出了一种方法，针对栖息地补丁保护使用地理信息系统。我们排名补丁的白垩草地在奇尔滕丘陵地区杰出的自然风光，使用简单的非生物标准，即：补丁面积，补丁形状，接近相同的栖息地和周围的土地利用类型的地区。我们编制了一份区域特定的指示物种清单，并根据其α多样性（从物种丰富度计算）对栖息地斑块进行了排名。我们比较了两种排名方案的结果，并确定了现有储备网络的关键聚合。这些可构成联合王国《生物多样性行动计划》所要求的未来生境扩展的基础。
Rare habitats are increasingly threatened by fragmentation and measures are required to conserve these valuable resources. Here, we present a method of targeting habitat patches for conservation using a Geographical Information System. We ranked patches of chalk grassland in the Chiltern Hills Area of Outstanding Natural Beauty using simple abiotic criteria, namely: patch area, patch shape, proximity to areas of the same habitat and surrounding land-use type. We compiled a regionally specific list of indicator species and ranked the habitat patches based on their alpha diversity (calculated from species richness). We compared the results of the two ranking schemes and identified key aggregations of the existing reserve network. These could form the basis of future habitat expansion as required by the United Kingdom Biodiversity Action Plan.
