森林遊樂爲山坡地土地利用方式之一種。山坡地保育利用方式係由外在之環境因素及內在之地質土壤化育條件所影響。本研究區域－新化實驗林場一緊臨新化鎮東郊之虎頭埤，對於土地資源甚爲有限之台灣而言，極具開發利用之潛能。然由於林場地屬本省嘉南農田水利會虎頭埤水庫集水區之上游水源地帶，故於開發前，須預爲妥善防患負面影響所帶來之環境衝擊問題。本研究係以南部地區主要遊樂區所導出之旅遊人數估算模式，應用於新化林場靠近虎頭埤具開發潛能區域，其面積約佔該林場三分之二（約242公頃）之山坡地爲主要研究範圍，進行土壤物理特性對森林遊樂開發之分析。本研究首先進行土壤樣品採取（計有35處採樣點），除於現場從事土壤剖面細部調査之外，並就所取之各層土壤樣本於實驗室內完成各項土壤物理特性分析。同時亦於研究區內調査土地利用現況，再將各項資料加以整理分析後顯示：新化實驗林場由於地理位置及交通狀況因素甚爲優越，極具開發潛能，若能配合目前之林業經營模式與林相逐漸更新之型態，設置綜合性森林遊樂區，並以其土壤物理特性之變化而局部性開發作爲森林休憩遊樂之配置準則，初期可開放遊憩面積約爲135公頃，年遊客人數估計約爲164,354人次；若克服土壤物理性限制因素，將可擴充遊樂面積至194公頃，倘能於區內提供100人之住宿，年遊客人數估計可達197,176人次。顯然新化實驗林場之森林遊樂土地利用方式將較純林業經營爲可行，不僅提供社會大衆一處健康之活動場所，同時亦不致對整體林場環境產生過大之衝擊而影響水庫集水區之整體經營管理原則。

Hillslope land use capability is governed by the environmental factors and its soil physical characteristics. Hin-Hua experimental forest area which is located in the eastern Tainan city near the town of Hsin-Hua. It is about 18 KM east of Tainan city. Owing to the limited land resources and well-connected traffic systems in this district make it possible to be with high potential of land development. Two thirds of the forest area (about 242ha) wore selected to be studied in this program. Soil survey, land use investigation, soil physical properties characterization, and environmental factors evaluation were conducted during the period of this study. However, Hsin-Hua experimental forest area is adjacent to the Fu-Tou-Pi reservoir. It is necessary to concern about the critical problems caused by the environmental impacts on intensive land use if this area is going to be developed in the future. As a result, it is expected that this research can provide a reasonable land-use model, based on the soil physical characteristics, which is able to be used to evaluate the possibility of forest recreation in this area.
