用原图-对偶图法设计内部间隔最小的自然保护区

生境破碎是导致生物多样性损失的重要原因之一,在设计自然保护区时设法减少生境破碎是提高保护区有效性的重要方法.由于经济资源或地理因素制约不可能把连续的大片土地都划为保护区时,设计一个由相互分离的几部分组成的保护区是更为现实的做法.选择地块组成内部间隔最小的保护区是减少破碎化的一个重要途径,但结合空间特征的保护区地块选择模...

A model for designing nature reserves with minimal fragmentation using a primal-dual graph approach

Habitat fragmentation is one of the most important causes of biodiversity loss.In order to maximize a nature reserve's effectiveness it is important to minimize habitat fragmentation during the design phase.However,due to economic or geographic constraints,it is often infeasible to acquire a large area of contiguous land for a reserve;designing a nature reserve consisting of several smaller components is often a more realistic choice.Selecting these smaller components with which to assemble a reserve with m...
