Abstract: A forest is a type of ecosystem in which there is high density of trees occupying a relatively large area of land. An ecosystem is an ecological unit consisting of a biotic community together with it’s a biotic environment. In the case of forest, tress dominant the biotic landscape, although there are also other plants and animals. There are many types of forest, such as tropical, evergreen, deciduous and dry forest based on the climatic condition and types of trees present. Forests provide innumerable values to people, provide aspects that address both physical needs as well as the internal nature of people. Forest help cleanse the air by intercepting airborne particles, reducing heat, and absorbing such pollutants as carbon monoxide, sulfur dioxide and nitrogen dioxide. Trees remove this air pollution by lowering air temperature, through respiration, and by retaining particulates. Erosion control has always started with tree and grass planting projects. Tree roots bind the soil and their leaves break the force of wind and rain on soil. Trees fight soil erosion, conserve rainwater and reduce water runoff and sediment deposit after storms. Herbs, shrubs and trees in the forests hold the topmost layer firmly by their roots. This does not allow natural forces like wind and water to carry away the topmost fertile layer of the soil easily. Hence, Forests prevent soil erosion. With forest conservation, animal species, insects and all the biodiversity of natural areas is protected. It is noteworthy that these beings and the local vegetation exert influence on conservation beyond deforestation and the regional climate, even interfering with the health of the local community.

Soil erodibility K factor is an important parameter for evaluating soil erosion vulnerability and is required for soil erosion prediction models. It is also necessary for soil and water conservation management. In this study, we investigated the spatial variability characteristics of soil erodibility K factor in a watershed (Changyan watershed with an area of 8.59 km2) of Enshi, southwest of Hubei, China, and evaluated its influencing factors. The soil K values were determined by the EPIC model using the soil survey data across the watershed. Spatial K value prediction was conducted by regression-kriging using geographic data. We also assessed the effects of soil type, land use, and topography on the K value variations. The results showed that soil erodibility K values varied between 0.039–0.052 t·hm2·h/(hm2·MJ·mm) in the watershed with a block-like structure of spatial distribution. The soil erodibility, soil texture, and organic matter content all showed positive spatial autocorrelation. The spatial variability of the K value was related to soil type, land use, and topography. The calcareous soil had the greatest K value on average, followed by the paddy soil, the yellow-brown soil (an alfisol), the purple soil (an inceptisol), and the fluvo-aquic soil (an entisol). The soil K factor showed a negative correlation with the sand content but was positively related to soil silt and clay contents. Forest soils had a greater ability to resist to erosion compared to the cultivated soils. The soil K values increased with increasing slope and showed a decreasing trend with increasing altitude.
