Early hominids have long been considered to have evolved in response to a directional shift from forested to open habitats (e.g., woodland, savanna grassland,glaciated terrain). Long-term paleoenvironmental records during the span of hominid evolution, however, contradict the idea of a simple directional trend followed by open-habitat stability. Rather, evidence from deep ocean cores, paleovegetation, and paleolakes all suggest a high degree and erratic pace of environmental fluctuation. The degree of fluctuation... Early hominids have long been considered to have evolved in response to a directional shift from forested to open habitats (e.g., woodland, savanna grassland,glaciated terrain). Long-term paleoenvironmental records during the span of hominid evolution, however, contradict the idea of a simple directional trend followed by open-habitat stability. Rather, evidence from deep ocean cores, paleovegetation, and paleolakes all suggest a high degree and erratic pace of environmental fluctuation. The degree of fluctuation was higher during the period of hominid evolution than any earlier time during the Cenozoic. Thus adaptation to disparity, or to the conflicting demands posed by natural selection, may provide a better explanation of hominid evoluReceived April 27, 1995Submitted for the special publication commemorating the 65th Anniversary of the IVPP, Academia Sinica, China. tion than adaptation to a single directional trend or stable environment. An example from the Pleistocene of southern Kenya illustrates how species survival and change may have been affected by environmental variability.

长时期以来．早期人类进化被认为是对于从森林到开旷的栖息地（如林地、稀树草原、冰川地区）的定向变动的反应．但是人类进化时期中的长期古环境纪录却与这种简单的定向趋势加上继之而来的稳定的开旷栖息地的观念相矛盾．而深海岩芯、古植物和古湖泊的证据全都暗示着高度的和步伐不规则的环境波动．在人类进化时期的环境波动的程度比新生代的任何较早的时期为大．对自然选择提出的互相冲突的要求的适应可以提供比对简单定向趋势或稳定环境的适应更好的解释．南肯尼亚更新世的一个例子显示，环境变异可以如何影响物种的持续和变化．

Acid sulfate soils (ASS) are widely distributed along the coastal areas in tropical and subtropical world. When the iron sulfides (FeS 2) in ASS are exposed to air, oxidation process and acid hazards would take place, which could result in the damages of the environment,and would be very harmful to human, animals and plants. The occurrence of acid hazards are commonly involved in four processes: 1) the formation, accumulation and deposit of FeS 2 in ASS; 2) the oxidation of FeS 2 and formation of acids; 3)... Acid sulfate soils (ASS) are widely distributed along the coastal areas in tropical and subtropical world. When the iron sulfides (FeS 2) in ASS are exposed to air, oxidation process and acid hazards would take place, which could result in the damages of the environment,and would be very harmful to human, animals and plants. The occurrence of acid hazards are commonly involved in four processes: 1) the formation, accumulation and deposit of FeS 2 in ASS; 2) the oxidation of FeS 2 and formation of acids; 3) the neutralization to the resulting acidity by soil buffering system; 4) the dilution and transportation of the acids. The actual acidity occurring in ASS is determined by the relative intensity and comprehensive result of the four processes. The acid hazards in ASS can cause the acidification of soil, water and atmosphere and the release of harmful metal ions, especially,those of heavy metals. Commonly, in the areas of ASS, owing to the acid influences, the eco-environment is degraded and the habitats are lost, plants and animals grow abnormally with low productivity and take disease frequently, the structure and function of regional ecosystems change and biodiversity declined gradually.

酸性硫酸盐土广泛分布于热带亚热带滨海地区，当其中的硫铁矿物质与空气接触或直接暴露地表时会发生氧化而形成强烈酸害，从而导致土壤、水、大气和区域生态系统的退化，最终对动植物生长和人类的健康产生较大影响而成为全球性的热带亚热带滨海环境问题。酸性硫酸盐土的酸害暴发主要包括：（１）硫铁矿的形成、累积与埋藏过程；（２）硫铁矿的氧化与致酸过程；（３）土壤对酸的中和与缓冲过程；（４）土壤中酸的稀释与迁移过程。酸性硫酸盐土的酸害影响是上述四个过程相对强弱与综合作用的结果。酸性硫酸盐土酸害暴发可导致区域土壤环境、水环境和大气环境的酸化，以及大量金属与重金属元素的溶解与释放，引起生物生存环境的恶化与栖息地的丧失，动植物出现变态生长，而且疾病频繁，生产力下降，区域生态系统的结构和功能发生异常，生物多样性下降。

During geological history, changes of geological environment were caused by the interaction between internal geological agent and external one. At present, the human activities resulted in deformation of earth′s surface form, damage of vegetation, occurrence of neo geochemical process, change of circulation and constituent of water, variation of gas composition and decrease of species, which seriously influenced quality of environment of human existence.

从地质环境的基本属性和特征入手 ,重点探讨了人类活动对地质环境的影响。结论指出 :地质环境是生物圈、大气圈、水圈和岩石圈相互交汇而成的地质空间 ,具有空间性、稳定性、可变性和系统性等特征 ,是包括人类在内的所有生物的栖息地 ;由于人口的剧增和科学技术的发展 ,人类活动导致地质环境发生着深刻的变化 ,即改变着地球表面的形态、破坏了地表的植被、产生了新的地球化学过程、改变着水的循环途径和物质成分、改变着大气的成分和使物种减少。认为地质环境的变化直接影响着人类生活环境的质量 ,甚至对人类的生存构成威胁
