The multifarious nature of biodiversity is considered in relation to difficulties of definite determination and managerial mandates for monitoring. At a micro scale there is some convergence with the concept of community, but the linkage is largely lost in the spectra of temporal scope, spatial scales, successional seres, and taxonomic trajectories. Practicality points to selecting suitable suites of indicators as surrogates for particular purposes. Domains of partial ordering on multiple indicators constitute comparable collectives, whereas different domains require recognition of special situations. Theoretical treatise and practical process can proceed in parallel, with dialogue and cross-fertilization serving to invigorate and inspire; whereas compulsive concern for completeness and consistency can be counter-productive as well as unduly expensive. Inability to completely capture all aspects of biodiversity in one full formulation is interesting and integral to issues of biocomplexity.
考虑到明确界定的困难和监测的管理要求,生物多样性的多样性本质被纳入考量。在微观层面,它与群落概念有一定的趋同性,但在时间范围、空间尺度、演替系列和分类轨迹等方面,这种联系大多消失了。实际操作表明,应选择合适的指标组作为特定目的的替代物。多个指标上的部分排序域构成了可比较的集合,而不同的域则需要认识到特殊情况。理论论述和实践过程可以并行推进,通过对话和相互促进来激发活力;而一味追求完整性和一致性可能会适得其反,成本也过高。无法在一个完整的表述中完全涵盖生物多样性的所有方面,这既有趣,也是生物复杂性问题不可或缺的一部分。
