Abstract
Kapuas Hulu Regency is lowland area of tropical rain forest which has many Dipterocarpaceae, one of which is tengkawang ( Shorea spp). Forests in Kapuas Hulu are currently under threat because of the widespread exploitation of land on a large scale without considering the balance of the ecosystem. Tembawang forest in Labian village has the potential of tengkawang trees which have not been known to be distributed based on topography where is grows. The aim of this study is to obtian the distribution of tengkawang (Shorea spp) species based on topography in the tembawang forest in the Labian district of Kapuas hulu, Kalimantan. This research was conducted using a survey method with samples taken in census in six tembawang. The research results show that there are 4 species of tengkawang (Shorea spp). The disribution of tengkawang spesies based on the from of thopography of Shorea marcophylla Aston and Shorea seminis Slooten grew on the topografhy of the valley with a height of 0 - 87 meter above sea level and slope of 9% - 23 % in all tembawang spread in group closed to waterside and scattered clustered at the Shorea pinanga Scheff and Shorea stenoptera Bruck spread on slope in groups with a height of 60-70 meter above sea level. Keywords : distributions, dipterocarpaceae, tembawang, tengkawang

Summary
Ketinggian dibawah 1300 m dpl., dan curah hujan > 1000 mm per tahun (Whitmore1975) dalam (Purwaningsih, 2004). Tengkawang (Shorea spp.) merupakan salah satu jenis tanaman kehutanan yang tumbuh di hutan hujan tropika. Tengkawang (Shorea spp.) merupakan salah satu jenis dari Famili Dipterocarpaceae yang tersebar pada kawasan hutan tembawang Desa Labian Kecamatan Batang Lupar Kabupaten Kapuas Hulu, dimana sampai saat ini belum ada data informasi mengenai persebaran berdasarkan tofografi (lembah, lereng, bukit) di sampaikan dalam peta untuk mendata sebaran tengkawang berdasarkan tingkat tumbuh pada setiap lokasi tembawang. Pentingnya mendata persebaran tengkawang pada setiap tembawang yang terdapat pada desa Labian, mengingat jenis dan potensinya dan kemungkinan untuk dilestarikan, dimanfaatkan dan dikembangkan atau dibudidayakan, maka dari itu perlu dilakukan penelitian tentang sebaran jenis tengkawang (Shorea spp.) pada hutan tembawang Desa Labian Kabupaten Kapuas Hulu. Tujuan penelitian ini adalah untuk mendapatkan data sebaran jenis tengkawang berdasarkan topografi tempat tumbuh jenis tengkawang (Shorea spp) pada hutan tembawang Desa Labian.
