Analisis Jasa Ekosistem Cacing Tanah Pada Lahan Ruang Terbuka Hijau Perkotaan Dalam Kaitannya Dengan Konservasi Tanah Dan Air

Earthworms occurring in urban green spaces potentially provide ecosystem services related to soil and water conservation, such as increasing soil fertility and increasing soil porosity that enhances infiltration. The objectives of the present study were to analyze the effects of vegetation cover types on the distribution, abundance, and biomass of earthworms and to assess the significance of their soil engineering activities in urban green spaces with particular reference to soil fertility and soil porosity. Observations were conducted in one of the major green spaces in Pekanbaru City with 25 observation points representing each vegetation cover type, i.e. group of trees, single trees, shrubs, grasses, and bare land.
Results showed the significant influence of vegetation and vegetation type on the distribution, abunance as well as abundance earthworms. They were significantly more abundant beneath trees, either in groups or single, than beneath shrubs or grasses, whereas they were hardly present in bare land. Earthworm activity level as reflected in cast production increased in accordance with the abundance and biomass. The ecosystem service related with soil conservation was demonstrated by higher concentration of Corganic, Ntotal, Ptotal, Pavailable dan Ktotal in soils inhabited by more earthworms, while the service associated with water conservation was clearly indicated by larger macropore volume and length and higher macropore density in soils dwelled by more earthworms.

Keywords: abundance, biomass, cast production, macropore, soil fertility, soil porosity, vegetation cover
