Abstract

Hainan Island, China, has a total area of 34 104 km2 and a dipterocarp forest which covers mainly the mountainous area below 1000 m a.s.l. over a total area of about 6500 km2. The forest consists of mixtures of species and single-dominance of species such as Vatica hainanensis, Hopea exalata, Heritiera parvifolia, Amesiodendron chinense and Litchi chinensis var. euspontanea. The forest possesses all features of the physiognomy and structure of a tropical rain forest, but not so typical as those of the equatorial forests. It can be divided into five types: hygrophilous mixed Vatica forest, hemihygrophilous mixed Vatica forest, mesophilous mixed Vatica forest, single-dominant Hopea forest, and single-dominant Vatica forest. Floristic and structural characteristics of the forest can clearly be correlated with the five forest types. Pulau Hainan, China mempunyai kawasan seluas 34 104 km2 dan hutan dipterokarpa di kawasan pergunungan kurang daripada 1000 m dari aras laut. Hutan ini mengandungi spesies campuran dan spesies dominan tunggal seperti Vatica hainanensis, Hopea exalata, Heritiera parvifolia, Amesiodendron chinense dan Litchi chinensis var. euspontanea. Hutan tersebut mempunyai semua ciri fisiognami dan struktur hutan hujan tropika, tetapi tidak begitu tipikal seperti di hutan khatulistiwa. Ia boleh dibahagikan kepada lima jenis: hutan Vatica higrofilus campur, hutan Vatica hemihigrofilus campur, hutan Vatica mesofilus campur, hutan Hopea dominan tunggal dan hutan Vatica dominan tunggal. Ciri flora dan ciri struktur hutan tersebut dapat dikaitkan dengan lima jenis hutan tersebut dengan jelas.
