| In the history of ethnology,scholars have never stopped arguing about the academic thought of binary opposition.In the contemporary era,the academic thought separation within the discipline has become more prominent;the theory proposition has gone from dialogue to opposition;the method selection has gone from common standards to independent;and the writing of ethnography has stepped into the “crisis of expression” in the continuous criticism and reflection.Therefore,scholars have to criticize criticism and reflect on reflection,calling again for adhering to the interdisciplinary research thinking and practicing the positivist research method.With the concepts of "human history","anthropocene" and "10,000 year scale" put forward,the ethnographic writing of grand narrative is back again.In this context,ethnologists have studied on domesticated crops,the origin of agricultural crops the birth of the country,the diet structure change and the relationship of the ecological environment change from the perspectives of micro and macro study,synchronic and diachronic study,and the interaction between practiced subjects and structure systems.These series of research are of great theoretical and practical significance.The Guanglang-Type palms in the tropical and subtropical regions are only common species upon earth.However,after they were domesticated by human beings,they underwent a historical process from prosperity to decline,which is the concentrated embodiment of the social and cultural succession of human beings.Specifically,around 10,000 years ago,humans began to move away from relying entirely on hunter-gatherer types of livelihood,but choosing instead to domesticate a limited number of plant species to produce food.The Guanglang-Type palms,also in this period were domesticated into food crops.In about five thousand years ago,the agricultural production system of staple food with The Guanglang-Type palms had been formed.The related ethnic groups also constructed unique cultural types such as political forms,economic behaviors,religious beliefs,artistic activities and food customs.However,after these " The Guanglang-Type palms agricultural nations" from ancient China and areas of southeast Asia were governed by countries,their staple crops,the Guanglang-Type palms,were not accepted and approved by new countries.And also in the process of competing for land with other crops,they gradually withdrew and eventually withdrew from the using range of relevant ethnic groups.Based on the time clues,the declined history of The Guanglang-Type palms can be divided into three stages: the rise period(ten thousand years ago),the prosperity period(five thousand years ago),the declined stage(country rule began to emerge).The rise and fall of The Guanglang-Type crops were directly related to the origin of agriculture,the country’s development and the rise of maritime trade in southern China andsoutheast Asia.In this paper,Chapter 3,Chapter 4 and Chapter 5 mainly refer to the discussion on these three periods.Chapter 6 is intended to analyze and respond to the issues raised and faced from Chapter 2 to Chapter 5.Chapter7,it is based on the contemporary construction of ecological civilization and poverty alleviation action target,putting forward the strategies of the contemporary revival of The Guanglang-Type crops.It can openly respond to the current outstanding practical problems in ethnology by a tracing study on The Guanglang-Type species: first,from the time series of a long period,with the rise and fall of The Guanglang-Type palms as the carrier,to clarify the signs and origin of symbols,and behind the power and meaning of the movement of mutual creation of dialectical relationship,hopefully to break down the "dualism" barrier of the subject/object opposition;second,the causal relationship between the rise and fall of The Guanglang-Type palms can be proved or falsified,which indicates that the cultural analysis of ethnology still needs to return to the disciplinary attribute of "empirical" research;thirdly,the revival strategies for The Guanglang-Type palms in this paper showed that ethnology can contribute in the contemporary social action subject.From a long time perspective,this paper examines the history of the rise and fall of The Guanglang-Type crops,and its reasons mechanism,and puts forward strategies of contemporary revival of the Guanglang-Type palms.It not only responds to the controversial focus of contemporary ethnology theory,but also hopes to make more new attempts on the writing of ethnography and write a kind of new “ experimental ethnography”. |
