破坏北苏门答腊省Gunung Leuser国家公园地区，方法是开垦土地和将土地覆盖从天然林变为农地。对土地利用和土壤生态系统承载能力的不重视可能导致土壤退化和动植物的破坏，以及野生动物栖息地的破坏。环境破坏将导致国家公园野生动物将走出保护区，并将损害农业社区。在天然林和农业区有目的地采样土壤。观察表明，对天然林植被的破坏导致土壤得不到保护，从而发生了侵蚀。天然林被破坏为农业用地，对土壤物理性质、土壤化学性质和生物土壤性质造成了严重的破坏。破坏天然林造成的土壤退化形式，即土壤密度(密度林巴克)增加103%，有机碳减少93%，土壤氮素减少81%。造成土壤退化的主要因素是有机质的减少和天然森林植被丧失造成的土壤侵蚀。第150/2000号治理条例中关于土壤退化的标准可以用来确定天然森林生态系统中土壤退化的程度。
Destruction of the Gunung Leuser National Park area of North Sumatera Province through land clearing and land cover change from natural forest to agricultural land. Less attention to land use and ecosystem carrying capacity of the soil can cause soil degradation and destruction of flora, fauna, and wildlife habitat destruction. Environmental damage will result in a national park wild life will come out of the conservation area and would damage the agricultural community. Soil sampling conducted in purposive sampling in natural forest and agricultural areas. Observation suggest that damage to the natural forest vegetation has caused the soil is not protected so that erosion has occurred. Destruction of natural forest into agricultural are as has caused damage to soil physical properties, soil chemical properties, and biological soil properties significantly. Forms of soil degradation caused by the destruction of natural forests, which is an increase in soil density (density Limbak) by 103%, a decrease of 93% organic C and soil nitrogen decreased by 81%. The main factors causing soil degradation is the reduction of organic matter and soil erosion due to loss of natural forest vegetation. Criteria for soil degradation in Governance Regulation Number 150/2000 can be used to determine the extent of soil degradation in natural forest ecosystems.
