| Summary: | Karst area is one of landscapes that have potency and ecological functions
in maintaining the balance of nature and human existence who live in it. The
growth of population results the increase of intensity in natural resources
utilization. Karst area that provides natural resources for the fulfillment of human
needs will be damaged if its utilization is highest. High or low levels of damage to
karst area both in densely populated area or not can be known through evaluation
of damage to karst area. This research is aimed to 1). Study characteristic of
damage to karst area in sub-district of Lohia and Bone. 2). Analyze the cause of
damage to karst area in sub-district of Lohia and Bone.
The method of research used in evaluation of damage to karst area in
Muna Regency is method of surveys, interviews and scoring towards determining
parameters of damage to karst area. These parameters include the extent of
vegetation cover and rock outcrop obtained from data of Citra SPOT 4,
fluctuation of spring debit, quality of spring water, and condition of cave
biodiversity known from field data and interviews.
The results of data analysis in Citra SPOT 4, field and scoring data on
determining parameters of damage indicate that Sub-district of Lohia and Bone
characterize the development of tropical and shape of topography to karst area in
Sub-district of Lohia is transition karst, while Sub-district of Bone characterizes
merokarst characteristics. Based on the criteria of parameters in determining
damage to karst area, Sub-district of Lohia is classified in minor damage proved
by a scoring value of 17 consisted of the value of 3 (three) to the extent of
vegetation cover, 1 (one) to condition of rock outcrop, 5 (five) to quality of spring
water, 5 (five) to quantity of spring water and 5 (five) to value of condition in
cave biodiversity. The damage of karst area in Lohia is caused by the activity of
limestone mining, taking from the stalactite and stalagmite of cave, and migratory
farming systems while in Bone it is caused by migratory farming systems also.
