Abstract

Nowadays, many people and institutions have interest on karst region, in the
karst region have many variety of geological (geodiversity), and biological
(biodiversity), and economic potential for current time and in the future.
However, the karst region are well known vulnerable to environmental damage,
So that, karst region are needed a right multi sectors management, which are,
bring a guarantee of increasing communities prosperity and suistainable
development, without ignoring karst conservation.

The role of environemtal geology for karst regions management is preparing
data of environmental geological setting, such as geology, geomorphologic
feature, hydrogeology and geological hazard. These data are ones basic data
for land use and spatial planning or karst region, beside for determining karst
regions boundaries and karsts classifiaction.

Classification and land use determination are a buffering system for karst region
conservation with keeps of allowed land use. In the reommended land use, for
each class region of karsts shoild be consider geological factors that have a role
as supporting and contrains for development. A supporting aspects are using
such as morphology, water resources, soil thickness and fertility, and foundation
bearing capacity. Constrains aspect are suspectibility to landslide and soil
erosion.

Determination of karst region begins with separating limestone area (and
dolomite) with non-limestone rock. Furthermore to separate of limestone which
has karstification with limestone do not have karstification. Karst classification
only did on the karst limestone.
