根据对目前春池、土壤和地貌测绘的分析，推测并得出结论：中央山谷内春池的出现可能与特定类型的土壤、地质构造和地貌相关。提出了一个分层框架，可用于识别和分类当今的春季水池景观。当前春天的水池、土壤、地质构造和地貌之间的关系在整个景观中以可预测的模式发生，因此可以预测到过去。因此，分层框架提供了一个筛选工具来定位潜在的历史泉池区域并帮助场地恢复和缓解区域。这对于识别历史上的春天池景观尤其重要——由于土地利用和管理技术，如土地平整、排水和/或深度撕裂，这些景观不再支持春天池。春季水池景观与土壤、地质构造和地貌的相关性还可以提供一种方法，用于识别特征水文特征、与特殊状态物种分布的相关性、评估地理多样性和生物多样性、确定恢复的适宜性、开发适当的缓解技术和建筑密度。这种方法有利于优化区域土地利用规划、保护区的建立和缓解库的选址。引文。第 15-23 页：C.W.

It is hypothesized and a conclusion is reached, based upon an analysis of present-day mapping of vernal pools, soils, and geomorphology, that the occurrence of vernal pools within the Central Valley can be correlated with specific types of soils, geologic formations, and landforms. A hierarchical framework is proposed that can be used to identify and classify present-day vernal pool landscapes. The present-day relationships between vernal pools, soils, geologic formations, and landforms occur in predictable patterns across the landscape and can, therefore, be projected into the past. The hierarchical framework thereby provides a screening tool to locate potential historic vernal pool areas and help site restoration and mitigation areas. This is especially significant for the identification of historical vernal pool landscapes – which as a resul t of land use and management techniques such as land leveling, drainage, and/or deep ripping – no longer support vernal pools. Correlation of vernal pool landscapes with soils, geologic formations, and landforms may also provide a methodology for identification of characteristic hydrologic features, correlation with special-status species distribution, assessment of geodiversity and biodiversity, determination of suitability for restoration, and development of appropriate mitigation techniques, and construction density. This approach facilitates optimal regional land-use planning, establishment of preserves, and siting of mitigation banks. CITATION. Pages 15-23 in: C.W. Witham, E.T. Bauder, D. Belk, W.R.
