Penelitian ini mengkaji struktur dan komposisi vegetasi pada berbagai pola agroforestri di Hutan Kemasyarakatan (HKm) Aik Bual, Lombok Tengah. Penelitian bertujuan menganalisis struktur dan komposisi vegetasi serta implikasinya terhadap fungsi ekologis dan nilai ekonomi dari masing-masing pola. Metode penelitian menggunakan pengumpulan data dari 24 plot pengamatan berukuran 20m×20m dengan 38 responden petani yang dipilih menggunakan metode stratified random sampling. Data dianalisis menggunakan Indeks Nilai Penting (INP), indeks keanekaragaman Shannon-Wiener (H'), indeks kemerataan Pielou, dan indeks kesamaan komunitas Sørensen. Hasil menunjukkan terdapat lima pola agroforestri dengan struktur vegetasi yang tersusun dalam lima strata tanaman. Indeks keanekaragaman pada tingkat pohon (2,09), tiang (1,45), dan semai (1,31) tergolong sedang, sedangkan pada tingkat pancang (0,98) tergolong rendah. Pola agroforestri campuran (39%) menunjukkan fungsi ekologis terbaik, sementara pola dominan durian (16%) memberikan nilai ekonomi tertinggi. Penelitian ini menyimpulkan bahwa sistem agroforestri di HKm Aik Bual berhasil menyeimbangkan fungsi ekologis dan ekonomis melalui pemanfaatan ruang vertikal yang optimal, yang berimplikasi penting untuk pengembangan program Hutan Kemasyarakatan yang berkelanjutan.
