地球生物圈的重要组成部分——土壤，是对人类生计和生活都至关重要的动态生态系统。人类文明的崛起和衰败，无不与对土壤的合理利用和管理失当有关。据全球土壤分布地理及气候情况，适合农作物生长的土地并不多，然而全球人口的增长下世纪有可能达到１００亿。下个世纪，整个人类所面临的最大挑战将是如何在最贫困的国家中对付饥饿的幽灵、制止环境恶化以及人口的高速增长。本文力求阐明解决全球粮食需求、土壤对污水的处理和防止环境进一步恶化的方法。只有多学科的共同努力才能达到预期的目的。
The Earth’s important component of the Earth’s biosphere is a dynamic ecosystem that is vital to human livelihoods and livelihoods. The rise and decline of human civilization are all related to the rational utilization of soil and mismanagement. According to the global distribution of soil and climatic conditions, suitable for crop growth in the land is not much, but the global population growth in the next century may reach 10 billion. In the next century, the greatest challenge facing the entire human race will be how to deal with the ghosts of hunger in the poorest countries and halt the deterioration of the environment and the rapid growth of the population. This article seeks to clarify ways to address global food needs, soil treatment of sewers and the prevention of further deterioration of the environment. Only multidisciplinary work together to achieve the desired goal.
