Abstract
Land Characteristics of Batang Pelepat Watershed In Bungo District, Jambi (Sunarti): Land characteristics describe biophysics characteristics of watershed. But, land has been used for economic oriented. The objective of this research is to identify land characteristics of Batang Pelepat watershed. Data collection was carried out by survey based on land unit map and analyzed by descriptive analysis. The results showed that land in Batang Pelepat watershed consist of 23 land units and some land use types (forest, rubber and oil palm farming, settlement and shrub), soil parent materials variously (alluvium, granite, tuff andesite, basalt, and clay rock), soil depth ranges from 88 to 160 cm and soil texture is classified moderate fine to fine. Lands were dominated by slope of >15–30% and >45–65% and dystrudepts of soil group with soil fertility level very low to low because its pH about 3.80-6.20, base saturation about 7.86-32.79% and P- available about 2.80-25.00 ppm. Various land use has also caused different erosion and permeability levels.
Highlights
Land is one of natural resources in watershed in addition to vegetation, water and enviromental service that are humans capital to fulfill their necessities of life
The results showed that land in Batang Pelepat watershed consist of 23 land units (Figure 1) which dominated by slope of >15-30% (13,354 ha or 27.55%) and slope of >45-65% (14,242 ha or 29.39%) (Table 1 and Figure 2)
According to Harjadi et al (2007), land characteristics of watershed is determined by topography factor of a region and slope dominantly, because watershed that dominated by steep slope and hill and mountain topography would be relatively sensitive to erosion and potentially to critical watershed
Summary
Land is one of natural resources in watershed in addition to vegetation, water and enviromental service that are humans capital to fulfill their necessities of life. Land characteristics are one of factors that determines the characteristics of watershed. The increasing of population and development activities have caused land use practice for economic oriented. According to Kartodihardjo et al (2004), generally land use in watershed is less concern to linkages of elements constituent of watershed systems, whereas carrying capasity conditions of watershed depend on complex and interrelated some factors. Those principles of land utilization have caused degradation of land and some watershed in Indonesia
