本书首先从自然和人文两个角度简要回顾了岭南地区从先秦到元朝的历史，之后以侣世纪为中心，详细考察了从明朝初期直到1850年前后岭南社会经济发展与环境变化的互动过程。 本书指出岭南环境和经济史中有五个里程碑式的事件：宋元时期汉族移民对瘴气免疫能力的提高和水利设施的建设，使得他们能够深入到土地肥沃的河谷地带，并逐渐取代了土著民族；珠江上游农业开垦导致的水土流失，在蒙古人?侵时被南逃到珠江口的汉人拦截下来，最终塑造出了珠江三角洲；16世纪中期开始的商业化进程；促使珠三角的农民改稻种桑(蔗)，从而改变了土地耕作的模式；17世纪中期危机之后，岭南人口的持续增长促使清政府采取了鼓励垦荒的政策；人类的垦荒活动使得岭南地区的森林分布日趋零碎，生态系统被不断消耗，以华南虎为代表的物种不断消失。而在这些里程碑式事件的背后，发挥作用的是三种驱动力量：气候变迁、人口变动和经济的商业化。

This volume illuminates the relationship of China's radical past to its reformist present as China makes a way forward through very differently conceived and contested visions of the future. In the context of early twenty-first century problems and the failures of global capitalism, is China's history of revolutionary socialism an aberration that is soon to be forgotten, or can it serve as a resource for creating a more fully human and radically democratic China with implications for all of us? Ranging from the early years of China's revolutionary twentieth-century to the present, the essays collected here look at the past and present of China with a view toward better understanding the ideas, ideals, and people who have dared to imagine radical transformation of their worlds and to assess the conceptual, political, and social limitations of these visions and their implementations.
