摘要:為了探討山地公園景觀生態林規劃區的生態適宜性評價機制,對重慶鴻恩寺公園的地形地貌、土壤、植被進行調查。采用因子加權疊加法對研究區域進行生態適宜性分析,確定山地公園景觀生態林營造的適宜度等級。結果表明,重慶鴻恩寺公園景觀生態林保護、營造生態適宜性評價值(SL)等級劃分為理想(5.80~7.15)、較好(4.90~5.80)、一般(4.05~4.90)、較差(2.45~4.05)4個等級;具體的影響因子排序為坡度>覆蓋度>土壤有機質>高程>郁閉度>土壤類型>坡向>土壤厚度>土壤pH。研究結果可為重慶鴻恩寺公園景觀林規劃決策提供相應的依據。

Abstract: In order to exploring the mechanism for assessing the ecological suitability of landscape ecological forest schedule in mountainous park, an investigation on the geography, soil and vegetation cover of Hongensi park in Chongqing was carried out. The ecological suitability of research area was analyzed by the comprehensive evaluation of factors, and finally an classification for the fitness of landscape ecological forest planning in mountain park was given. The results suggested that, landscape ecological forest protection,construction of ecological suitability evaluation value of ?Hongensi park ?were divided into four ranks: ideal(5.80~7.15),fine(4.90~5.80),normal(4.05~4.90) and poor(2.45~4.05);and the ranking of relevant factors was as follows: slope>coverage>soil organic matter>height>canopy density>soil type>aspect>soil thickness>soil pH value. The research results could provide some basis for the landscape planning of Hongensi park.

山地公園是利用高聳的地貌形態和現有的植被條件,為城市居民提供游憩休閑場所的公園[1,2],但由于地形地勢多變和近年來人為的不合理開發,使公園出現土壤侵蝕、水土流失、植被破壞、景觀異質性降低等一系列問題[3-7]。 在傳統的山地公園植被規劃中,往往強調園林硬質景觀的塑造和風景林的營建,忽略了水源涵養、水土保持等生態效益的發揮[8,9],導致景觀生態林規劃利用的不適宜,生態效益欠佳,甚至其生態系統的不斷惡化[10]。
生態適宜性評價主要反映某種用途的適宜程度和選擇利用可能性,當前主要用于城鎮建設用地規劃、農業用地規劃以及風景區生態規劃等方面[11-14],但鮮見從景觀生態林規劃角度對山地公園進行生態適宜性分析的研究。因此,本研究以重慶鴻恩寺公園為例……
