Abstract

Dalam beberapa dekade belakangan penutupan lahan Sub DAS Krueng Jreue telah banyak mengalami perubahan. Tingkat pertambahan penduduk yang begitu pesat dengan luas sub DAS relatif tetap mengakibatkan semakin meningkatnya konversi lahan yang pada umumnya kurang memperhatikan faktor konservasi tanah dan air dalam pengelolaannya. Hal ini menimbulkan masalah besar dalam kehidupan seperti terjadinya lahan kritis. Pemetaaan lahan kritis pada Sub DAS Krueng Jreue diperlukan untuk memberikan tingkat pengelolaan yang tepat sehingga tidak mengganggu keseimbangan ekosistem yang ada. Hasilnya menunjukkan bahwa, kelas kekritisan lahan pada kawasan hutan lindung adalah kritis seluas 6.993,217 ha (26,97 %), agak kritis 3.216,202 ha (12,40 %), potensial kritis 2.352,916 ha (9,08 %), dan sangat kritis 14,351 ha (0.06 %). Luas kekritisan lahan pada kawasan budidaya pertanian adalah kritis 1.234,508 ha (4,76 %), potensial kritis 941,168 ha (3,63 %), tidak kritis 417,399 ha (1,61 %), dan agak kritis 46,582 ha (0.18 %). Luas kekritisan lahan pada kawasan penyangga adalah agak kritis 5.884,800 ha (22,70 %), kritis 2.148,083 ha (8,29 %), tidak kritis 1.430,358 ha (5,52 %), sangat kritis 1.046,304 ha (4,04 %) dan potensial kritis 201,058 ha (0,788 %). Fungsi kawasan terluas di Sub DAS Krueng Jreue adalah kawasan hutan lindung di Kecamatan Indrapuri dan tingkat kekritisan lahan di Sub DAS Krueng Jreue yang sangat kritis terdapat pada kawasan penyangga pada Kecamatan Indrapuri.
