Through the study of the ecological theories and the survey of research papers along with the observance of the German ecological country space, the researcher proposes the basic structure of the ecological environment sectors of the country house yard space : the researcher discusses the ecological conditions of the country house yard space in two ways-through the space sectors ( including the forms and properties of the sites and the kinds of the objects) and through the abiotic sectors ( including temperature, sunshine, water, air and soil). Then connecting the space factors with the abiotic sectors together, the researcher proposes five ecological environment sectors of the country house yard space, which are planting, pavement of the earth surface, soil composition, ponds and fences. The researcher takes the five sectors as the basic structure to analyze, to estimate and to plan the yard space of the country houses.
