| 摘 要： | 在热带条件下，不同种类岩石受到强烈的化学风化作用，并导致某些环境问题，香港在这方面提供了十分典型的例子。在香港，岩石风化厚度可达８０ｍｉｎ，普通成岩矿物长石和云母被转化为粘土矿物埃洛石和高岭石，风化岩密度一般降低４０％￣８０％，埃洛石密度看来是亚稳定的，随年龄的增加而降低。在老于晚侏罗纪或早白垩纪的岩石中，还未临别出埃洛石。埃洛石、高岭石及其风化产物少含植物所需营养元素，且阳离子交换能力低，因而所

| Abstract: | Hong Kong's international character and geological setting provide a unique opportunity to encourage cooperative research on environmental problems of hot, wet tropical/sub-tropical lands. The findings of my geological and mineralogical research in Hong Kong in the 1960-1970s offered newinsights and any rapport current efforts to restore degraded land in South China today. Increased cooperation among South China, Hong Kong, and other international researchers could provide much needed solutions for improving the productivity of degraded lands and the quality of life for the people who depend uPon taem |
