In order to solve the important and basic problem of the petrogenesis of "Tiantangzhai migmatitic granite" in the core of Dabie orogenic belt, the detailed 1∶50000 regional geological surveying and the big scale dissection of important region (metamorphic rocks, granites and structure), were operated in about 900km〓 area near Tiantangzhai peak. On the bases of the petrology, mineral chemistry, geochemistry of rare earth element and microelement, isotope geochemistry and chronology, physicochemistry, magmatic dynamics, geodynamics, diagenetic simulation, and regional geophysical data, the theory of cooling age and historical geochemistry and the viewpoint of tectonic evolution are applied to study the petrogenesis of Yanshan epoch granites of this region. On the bases of above studies, the process of tectonomagmatic dynamics after indo-Chinese epoch in Dabie orogenic belt is discussed. The important conclusions are gotten

The analyses of social and economic development indicate that, up to 1998, the total population in Yijinholo County is 143, 949 persons, the population density is 24 persons per square kilometer, large population number results in land exploitation for food and overgrazing in rangeland. The change in temporal and spatial pattern of landuse from 1977 to 1998 demonstrates that mobile sand dunes was replaced by rangeland and woodland and partial shrubland in the middle of study area changed into rangeland and farmland from 1977 to 1987, while mobile sand dunes and rangeland transformed into shrubland and farmland in a small parts from 1987 to 1998, the above-mentioned change is proved by the change of fractal dimension index and fragmentation index at landscape and its element levels.

对近50年来伊旗社会经济发展的分析结果表明，虽然人口增长率基本上呈下降趋势，但由于人口基数较大，截至1998年底，伊金霍洛旗的人口总数达143949人，人口密度为24人／平方公里，较高的人口密度带来了更多的生存需求，使得大量的草牧场被开垦，而剩余的则严重超载。1977-1998年间伊土地利用结构总体格局变化的分析结果表明，1977-1987时段内主要是流动沙地为草牧场和乔木林地所取代，伴随着中部的部分灌木林地转换为草牧场和农地：而1987-1998时段内主要是草牧场和流沙地为灌木林地和农地特别是灌木林地所取代，而景观及各景观要素的分维度指数和破碎度指数的变化也充分证实了这一结论，虽然在前10年（1977-1987年）中大面积的灌木林被砍伐，但土地利用格局的整体变化间接地反映出该时段内荒漠化的状况正在发生逆转。
