The ecosystems of Kimpolo I village and its surroundings are located 23 km east of Kinshasa on the western edge of the Bateke Plateau. To better understand the contribution of its soils and its relief to the ecological planning of its natural ecosystems, a soil analysis and a geomorphological map of this area have been carried out. This study was conducted using soil samples from environmental ecosystems and satellite geographic data collected in the field. On 15 soil samples from different horizons of four profiles, the analysis indicates that the texture of these soils is more than 85% sandy, the pH-H2O and KCl vary from strongly to moderately acidic, the carbon contents Organic matter levels are low, organic matter levels correspond to very low productivity and the Carbon-Nitrogen ratios indicate that there is either a predominance or a balance between mineralization and nitrogen release in horizons and cation exchange capacities. Reveal that these soils are sandy. Geomorphologically, spatial data processing informs that contour lines are spaced in the middle of the site, attesting to the existence of the plain and narrowed after watercourses before re-spacing to mark the sinusoidal change in relief. In view of the human activities practiced in the site which have a negative impact on the soils and the relief, particular attention must be given to these degraded ecosystems, with a view to their ecological planning.

The ecosystems of Kimpolo I and its surroundings are located 23 km east of Kinshasa on the western edge of the Bateke Tray. To better understand its floristic richness and its chorological position, an analysis of the florule, autoecological and phytogeographical spectra of the species was undertaken. This study was conducted using floristic material from botanical surveys. On an area of 8.65 km2 surveyed, 219 species were inventoried. They belong to 71 families and 168 genera. The most diverse families in number of species are Fabaceae, Poaceae, Rubiaceae, Euphorbiaceae, Cyperaceae, Apocynaceae and Asteraceae. Ecological spectra show the high representativeness of phanerophyts, geophytes, chamephyts, therophyts and hemicryptophyts. At the phytogeographic level, there is a predominance of regional guineo-Congolese species , followed by those with a very wide distribution and African with a large distribution. From the chorological point of view, this flora is north of the Bas-Congo sector and south of the guineo-Congolese regional center of endemism. In view of the many human activities practiced (shifting cultivation, harvesting and harvesting, irrational exploitation of ecosystems, introduction of exotic species, breeding, hunting, fishing, fish farming, charring of wood, bush fires) in the site whose extent on flora and vegetation is strong, special attention must be given to these threatened ecosystems, for their ecological development and their preservation as a regulator of local climate.
