Maintaining the beauty of city grassland is an important indicator in urban landscape management for local government, and the understanding of grassland ecology is a key element to achieve this purpose. To understand and effectively manage the grassland species is the first step toward a beautiful city environment. Therefore, this study is to investigate and analyze the species composition of grassland vegetation in park, derelict urban land, green lands beside the road, and school yards in Nanzih District, Kaohsiung. The results may serve as a reference for city grassland management.
The author studied the grassland vegetation at 120 sites in Nanzih District with the purpose of identifying distinct plant communities and used direct gradient analysis to analyze the relationship between environment conditions and plant communities. A total of 117 species belonging to 33 families of the vascular plants were recorded, and Poaceae is the family with the largest number of species. Six vegetation types were identified after the analyses of TWINSPAN, CA and DCA ¡G¢¹,Chamaesyce hirta - Chloris barbata type; ¢º, Panicum maximum - Bidens pilosa type; ¢», Eleusine indica - Eragrostis tenella type; ¢¼, Cynodon dactylon type; ¢½, Vernonia cinerea - Oxalis corniculata type; and ¢¾, Hedyotis corymbosa type.
Results from ordination indicated that vegetation distribution patterns and soil characteristics was not closely related. Although certain relationship must existed between species and soil, the correlations between different species compositions and environmental factors were not obvious in this study.
