人文地理学方法論と生態学的視点

社会学・人類学・エコシステム論との関係を通して

抄録

Traditionally, many geographers have been interested in the relations between methodologies of human geography and ecology, but their standpoints have been divergent. The purpose of this review is to clarify the context and directions of the ecological approach with reference to the methodology of sociology, anthropology and ecosystem theory in the U.S.A. and the U.K.
In the Chicago School of sociology, human ecology is defined as the study of community. Human ecologists make a distinction between community and society. Society is based upon the cultural consensus of the inhabitants, while community is based upon their biotic competition and symbiosis. But the biotic community concept has been severely criticized. In response to this criticism, human ecology has divided into two schools. The Neo-orthodox school mainly studies spatial structures of communities. And Socio-cultural school emphasizes the individuals' perception and image of the space.
Anthropologists, traditionally, have been interested in the geographical area and historical change of cultures. Steward has proposed a theory of cultural ecology which concerns adaptation of culture to environment. In contrast to him, other anthropologists propose a more biological, ecological anthropology that is based upon ecosystem theory or Darwinism.
In addition, some geographers have introduced community theory (Morgan, Moss) and ecosystem theory (Stoddart) from biology, especially ecology. These are theoretical frameworks that attempt to dissolve the distinctions between physical and human geography and between idiographic and nomothetic approaches, in order to defend the unity of geography. The Chicago School of sociology inspired the theory which investigates the morphology and function of urban areas, which has in turn influenced urban geography. Anthropology has inspired ecological methodology which investigates man's adaptation to environment from the viewpoint of activities for subsistence. Such movements have affected current cultural geography.
In sociology, anthropology and human geography, the ecological approach commonly concerns the process in which social behaviors adapt to and interact with space and environment, as well as the values and perceptions of man, and energy flows in that process.
In conclusion, the author would like to understand the ecological approach in the following currents:
1. Both geography and ecology are studies based upon region and place.
2. Both geography and ecology endeavor to comprehend nature and society integratively.
3. The ecological approach is wholistic.
4. The ecological approach studies historical changes.
5. The ecological approach treats circulation and economic phenomena.
6. The ecological approach investigates the relations between internals and externals of population, community and ecosystem.
7. The ecological approach is functional.
8. The ecological approach is systematic.
Many geographers, however, have criticized ecological approach for the following reasons: (1) Ecological approach is not deductive and analytical. (2) Ecological approach is based upon biological analogy, and is destitute of socioeconomic scope about human society. Therefore, in attempts to solve problems of environmental pollution geographically, it may be necessary to add wider social framework to ecological approach.
