金門國家公園土壤調查分析及植生適種研究(二)
金門地區潛在植被單位包括：海濱植群（海生植物群落、沙灘植物群落、泥灘植物群落、海崖植物群落、海岸林、海岸疏林）、河口濕地（紅樹林、草澤）、內陸植群（低地森林、凹谷森林、上坡及裸岩植群），不同植被單位各具有其特殊之種類。金門之植被有許多特色，例如乾旱環境種類偏多，多刺植物之數量頗多，具落葉樹、多岩生種類，水、濕生植物種類多，木本植物偏少，且植株較矮，是一個相當特殊的環境，因此造林或行道樹植栽的選擇，需考慮所在區域之特殊性。金門地區之土壤分類可歸類為2種土綱(極育土與新成土)、3種亞綱(暫乾極育土、砂質新成土與正常新成土)，以及5大土類(厚育暫乾極育土、簡育暫乾極育土、鐵網紋暫乾極育土、暫乾砂質新成土，與暫乾正常新成土)。金門地區的土壤pH值大多為酸性（pH 4.3~6.8）；金門地區之土壤有機質貧乏，不能提供足夠的養份供作物或植物生長，為金門地區作物生長之一大限制因子。
根據第一年度之調查及分析，本年度擬選定幾處需較大規模造林之地區，分析其土壤與植被之關係，並進形深入之探討，提出合適之植栽復育建議。

Abstract
The potential vegetation in Kin-Men includes seashore vegetation (marine vegetation, sandy beach vegetation, sea-shore forest, sea-shore parkland), estuarine wetland vegetation (mangrove, marsh), inland vegetation (lowland forest, valley forest, ridge and cliff vegetation). Diferent vegetations have their own special species. The vegetations there have many special characteristics. For example there are many kinds of arid species, thorns species, deciduous trees, rocky species and hydrophytes, but there are less woody plants and the height are low. Therefore it is important to consider the special characteristics of the area to choose the species of artificial forest the main soil in Kin-Men is Ultisols (Paleustult and Haplustult) and Entisols (Plinthustult, Ustipsamment and Ustorthent). The soil at inland forest is mainly belonging to Paleustult, and that at rocky environment in Mt. Tai-Wu is Haplustult. . Moreover the two kinds of Entisols have close relative with parkland. The pH in most soil is acid (pH4.3~6.8) and the organic material is too less to offer enough nutrient to crop and plant. This is the major limit factor that influences the growth of crops in Kin-Men.
According to the investigation of the first year, we consider to choose several areas where need a large-scale afforestation, and analysis the relation of soil and vegetation then doing deeply confer for suggesting the adapt vegetation restoration.
Key words: Kin-men, vegetation, soil characteristics, afforestation
