Abstract

Abstract: In order to provid a reliable basis in theory for sustainable management and sustainable nutrient management of successive planting of Cunninghamia lanceolata plantations in Guangxi Zhuang Autonomous Region,the eleven evaluation objects(such as soil bulk density,soil porosity,soil water retaining capacity and soil water storage etc.) were selected as the research objects,and modern comprehensive evaluation software of AHP module was used to calculate and analyze the correlation degree and size ranking of soil moisture physical condition of Cunninghamia lanceolata plantations under different plantings(G1 and G2)and different soil thickness(0～20cm and 20～40cm).The results showed that:(1) The soil bulk density of Cunninghamia lanceolata plantations under different rotations increased with the increment of soil depth.The soil bulk density of soil were greatly reduced by the continuous cropping of Cunninghamia lanceolata.(2) With the increment of soil depth,total porosity,capillary porosity,saturated moisture capacity,capillary holding capacity increased gradually.(3) In the layer of 0～40 cm,the soil total and uncapillary porosity of the second generation forest was larger than the first one,soil water retention capacity of the second generation forest was stronger than the first one,but the former was weaker.(4) The effect of soil bulk density on soil moisture physical condition was the most important,and the order of soil moisture physical condition in the field of successive planting Cunninghamia lanceolata was G2(0～20cm) ＞G2(20～40cm)＞G1(0～20cm)＞G1(20～40cm)。

Key words: Cunninghamia lanceolata, the continuous cropping, soil moisture, physical characteristics, gray correlation analysis
