为了探究不同经营措施下落叶松林枯落物的持水能力，以修枝抚育、引进灌木、孔状择伐、封闭抚育、带状皆伐5种措施，以未封禁作为对照，通过对未抚育、抚育后2a、抚育后4a落叶松林枯落物的储量、最大含水量、自然含水量、有效拦蓄量等指标进行测定。结果表明：落叶松人工林枯落物储量的大小，在采取措施以后2a与4a的表现出的状态均为：带状皆伐＞封育恢复＞孔状择伐＞修枝抚育＞引进灌木＞未封禁。在经过抚育以后4a间枯落物最大持水量大小分别为：引进灌木＞封育恢复＞带状皆伐＞孔状择伐＞修枝抚育＞未封禁。在经过改造措施的林分自然含水量均表现出高于对照区域，在改造的前两年，自然含水量大小为：封育恢复＞引进灌木＞孔状择伐＞带状皆伐＞修枝抚育，2～4a表现出的自然含水量的大小为：引进灌木＞封育恢复＞孔状择伐＞带状皆伐＞修枝抚育。在经过抚育改造之后的林分，有效持水量的大小排序为：带状皆伐＞孔状择伐＞引进灌木＞封育恢复＞修枝抚育。
為瞭探究不同經營措施下落葉鬆林枯落物的持水能力，以脩枝撫育、引進灌木、孔狀擇伐、封閉撫育、帶狀皆伐5種措施，以未封禁作為對照，通過對未撫育、撫育後2a、撫育後4a落葉鬆林枯落物的儲量、最大含水量、自然含水量、有效攔蓄量等指標進行測定。結果錶明：落葉鬆人工林枯落物儲量的大小，在採取措施以後2a與4a的錶現齣的狀態均為：帶狀皆伐＞封育恢複＞孔狀擇伐＞脩枝撫育＞引進灌木＞未封禁。在經過撫育以後4a間枯落物最大持水量大小分彆為：引進灌木＞封育恢複＞帶狀皆伐＞孔狀擇伐＞脩枝撫育＞未封禁。在經過改造措施的林分自然含水量均錶現齣高于對照區域，在改造的前兩年，自然含水量大小為：封育恢複＞引進灌木＞孔狀擇伐＞帶狀皆伐＞脩枝撫育，2～4a錶現齣的自然含水量的大小為：引進灌木＞封育恢複＞孔狀擇伐＞帶狀皆伐＞脩枝撫育。在經過撫育改造之後的林分，有效持水量的大小排序為：帶狀皆伐＞孔狀擇伐＞引進灌木＞封育恢複＞脩枝撫育。

In order to explore the different management measures on Larix principis‐rupprechtii under the lit‐ter water holding capacity to pruning and tending ,five measures were used ,taking no tending 2 a and 4 a litters of reserves after tending ,the maximum moisture content ,natural water content ,effective impounding and other indicators were measured .The results showed that the reserves of litter after 2 a and 4 a of taking measures ex‐hibited states were as follows:clearcutting> enclosure recovery> hole shape selective cutting > pruning and tending>introduced shrub>not banned .After tending maximum water holding capacity of 4 a litter were:in‐troduction of shrubs>enclosure recovery>clearcutting> hole shape selective cutting> pruning and tending>not banned .After the transformation measures natural moisture content exhibited higher than control area ,the first two years of reconstruction ,the natural moisture of litter:fencing restore> introduction of shrubs> hole shape selective cutting>clearcutting>pruning and tending ,within 2~4 a the natural water content showed:in‐troduction of shrubs> enclosure recovery> hole shape selective cutting> clearcutting> pruning and tending . After tending transformation ,water‐holding capacity order :clearcutting> hole shape selective cutting>intro‐ducction of shrub>enclosure recovery>pruning and tending .
