Keanekaragaman abiotik memiliki peran yang sangat
penting dalam suatu ekosistem. Kajian geodiversitas yang merupakan konsep
keberagaman abiotik cocok diterapkan di kawasan cagar budaya. Kawasan Situs
Sangiran memiliki nilai OUV atau makna penting yang tersimpan pada lahan-lahan terbuka
sehingga keberadaannya harus dilindungi. Penilaian indeks geodiversitas
merupakan langkah awal memetakan keanekaragaman abiotik sehingga dapat diketahui area
mana yang memiliki keunikan. Peta indeks geodiversitas dihasilkan dari persamaan yang melibatkan
jumlah keragaman elemen dan koefisien roughness.
Indeks geodiversitas di Kawasan Situs Sangiran terbagi
menjadi lima kelas, yaitu sangat rendah, rendah, sedang, tinggi dan sangat
tinggi. Geodiversitas tinggi dan sangat tinggi berada di tengah Kawasan Situs
Sangiran dengan sedikit melebar ke selatan karena mengikuti pola Sungai Cemoro.
Berdasarkan bentuklahan, geodiversitas tinggi-sangat tinggi paling banyak
ditemukan pada lereng dan lembah antarsungai (interfluve). Geodiversitas
sangat rendah-sedang banyak dijumpai di bentuklahan dataran alluvial.
Abiotic diversity has a very
important role in an ecosystem. Geodiversity study which is the concept of
abiotic diversity is suitable to be applied in cultural heritage areas. The
Sangiran Site area has an OUV value or important meaning that is stored in open
land so that its existence must be protected. Assessment of the geodiversity
index is the first step in mapping abiotic diversity so that it can be
identified which areas are unique. The geodiversity index map is generated from
an equation involving the amount of elemental diversity and the surface
roughness coefficient.
The geodiversity index in the
Sangiran Site Area is divided into five classes, namely very low, low, medium,
high and very high. High and very high geodiversity is in the middle of the
Sangiran Site Area with a slight widening to the south because it follows the
pattern of the Cemoro River. Based on the landform, high-very high geodiversity
is most commonly found on slopes and interfluve valleys. Very low-moderate
geodiversity is often found in alluvial plains.
