Indeks Keanekaan Shannon & Wiener H1 = - Σ (ni/N) ln (ni/N) = - Σ Pi ln Pi Keterangan: H1 = Indek keanekaan ni = jumlah individu dari masing-masing spesies N = total individu dari semua spesies Kriteria : H1 < 1 = tercemar berat/gangguan berat H1 = 1 – 1,5 = tercemar sedang/gangguan sedang H1 = 1,5 < x < 2,0 = tercemar ringan/gangguan ringan H1 > 2 = belum tercemar/belum terganggu (Lee et al., 1978)
Indeks keanekaan Simpson D = Σ ( ni/N)2 I = 1 – D I = Indeks keanekaan Simpson D = Resiprok ni = jumlah individu dari masing-masing spesies N = total individu dari semua spesies
