摘要
抽象。降雨在植被标题上的过程被称为拦截。这项研究的目标是在7、15和30岁的时候对一棵松树进行拦截、滑水和茎流。这项研究是在亚齐大森林公园地区进行的。本研究使用的材料和工具是降压器、卷尺杯、卷尺、显微计和微软Excel软件。这项研究得出的结论是,树木的寿命对流失(throughfall)和茎流(stemflow)的水量有重大影响。树木的直径与茎流(stemflow)的水量有显著关系。树的年龄极大地影响了树冠密度,树冠越密集,截断就越大。针状松叶的紧密生长也会影响截取。Rainfall在松树看台上拦截。rainfall retion的过程被称为“拦截”。这项研究是对松果感兴趣、throughfall和stemflow on pine trees的研究,分别是7年、15年和30年的老年生活。这项研究是在大森林公园地区进行的,大约一天。在这个研究中使用的材料和工具是自动的根据研究,人们普遍认为树木的年龄严重影响了铁路和铁路。树的直径严重影响了秋天和斯坦法洛的陡峭山坡。树冠的密度很大。再否认树冠,然后再否认树冠的伟大拦截。暴露在拦截感兴趣的松树形状的叶子令人毛骨悚然。
Intersepsi Curah Hujan Pada Tegakan Pohon Pinus (Casuarina cunninghamia)
ABSTRAK. Proses tertahannya curah hujan di atas tajuk vegetasi dikenal dengan istilah intersepsi. Penelitian ini bertujuan untuk melakukan pengukuran intersepsi, air lolos (throughfall), dan aliran batang (stemflow) pada tegakan pohon pinus (Casuarina cunninghamia) pada kelas umur 7, 15 dan 30 tahun. Penelitian ini dilaksanakan di kawasan Taman Hutan Raya, Seulawah, Kabupaten Aceh Besar. Bahan dan alat yang digunakan pada penelitian ini adalah alat penakar curah, gelas ukur, pita ukur, klinometer, dan perangkat lunak Microsoft Excel. Berdasarkan hasil penelitian diperoleh bahwa umur pohon berpengaruh secara signifikan terhadap besarnya jumlah air lolos (throughfall) dan aliran batang (stemflow). Diameter pohon berpengaruh secara signifikan untuk besarnya jumlah air lolos (throughfall) dan aliran batang (stemflow). Umur pohon sangat mempengaruhi tingkat kepadatan tajuk dimana semakin lebat tajuk pohon maka intersepsi semakin besar. Bentuk daun pinus yang berbentuk jarum yang tumbuh dengan rapat juga mempengaruhi intersepsi.Rainfall Interception On The Stands of Pine Tree (Casuarina cunninghamia)ABSTRACT. The process of rainfall retention above the canopy of vegetation is known as interception. This study aimed to measure interception, throughfall, and stemflow on pine trees (Casuarina cunninghamia) at different ages 7, 15 and 30 years old, respectively. This research was conducted in the area of Taman Hutan Raya, Seulawah, Aceh Besar. Materials and tools used in this study were an automatic raingauge, measuring cups, measuring tape, clinometer, and Microsoft Excel software. Based on the research, the results showed that the age of the tree had significantly influenced the throughfall and stemflow. The tree’s diameter had significant influence on the large amount of throughfall and stemflow. The tree’s age greatly affected the density of tree canopy. The more dense the tree canopy, then the greater interception the tree had. The pine needle-shaped leaves densely grew that influenced the interception.
