Most of the global human population lives in urban areas where biogeochemical cycles are controlled by complex interactions between society and the environment. Urban ecology is an emerging discipline that seeks to understand these interactions, and one of the grand challenges for urban ecologists is to develop models that encompass the myriad influences of people on biogeochemistry. We suggest here that existing models, developed primarily in unmanaged and agricultural ecosystems, work poorly in urban ecosystems because they do not include human biogeochemical controls such as impervious surface proliferation, engineered aqueous flow paths, landscaping choices, and human demographic trends. Incorporating these human controls into biogeochemical models will advance urban ecology and will require enhanced collaborations with engineers and social scientists.
全球大部分人口居住在城市地区，在这些地区，生物地球化学循环受社会与环境之间复杂相互作用的控制。城市生态学是一门新兴学科，旨在理解这些相互作用，而城市生态学家面临的一大挑战是开发能涵盖人类对生物地球化学的众多影响的模型。我们在此指出，主要在未受管理的和农业生态系统中开发的现有模型在城市生态系统中效果不佳，因为它们未纳入诸如不透水表面扩散、工程化水流路径、景观美化选择和人类人口趋势等人类生物地球化学控制因素。将这些人类控制因素纳入生物地球化学模型将推动城市生态学发展，这需要加强与工程师和社会科学家的合作。
