According to the factors such as, climates,soil and forest types,the forest ofHenan Province was divided into two forest vegetation regions and eight forest ecosys-tems.Based on forest ecosystem classification,the stability of each forest ecosystem typewas studied by using the method of grey clustering analysis to selecte six indices which af-fected the stability of forest ecosystem. The results showed that :1)Wind and sands break-ing forest ecosystem in Huang Huai plain and evergreen and leaf-fall broadleaf forestecosystem in Nanyang Basin were stable types.2)Leaf-fall broadleaf forest ecosystem inmountain and hilly regions of Tai Hang was fragil3)Leaf-fall broadleaf forest ecosystemin the loess hilly regions of west Henan Province was relatively fragile type.4)Leaf-fallbroadleaf forest ecosystem on the north slope of Funiu Mountains was mid-stable type.5)Low-waterlogging farmland protection forest ecosystem in Huai Bei areas evergreen andleaf-fall broadleaf forest ecosystem on the south slope of Funiu Mountains ,and evergreenleaf-fall broadleaf forest ecosystem in Tong Bai and Da Rie mountain regions were relative-ly stable type.

根据气候、土壤、森林类型等因素,将河南省森林划分为2个森林植被区和8个森林生态系统类型区。在此基础上,选取影响森林生态系统稳定性的6个主要参数,运用灰色聚类的方法,对河南省诸森林生态系统类型进行稳定性分析。结果表明:1)黄海冲积平原防风固沙林森林生态系统和南阳盆地常绿、落叶阔叶林森林生态系统属于稳定类型。2)太行山山地丘陵落叶阔叶林森林生态系统属脆弱类型。3)豫西黄土丘陵落叶阔叶林森林生态系统属较脆弱类型。4)伏牛山北坡落叶阔叶林森林生态系统属中等稳定类型。5)淮北低洼易涝农田防护林森林生态系统、伏牛山南坡常绿、落叶阔叶林森林生态系统和大别、桐柏山地常绿、落叶阔叶林森林生态系统属较稳定类型。

Multi-functional protection forest system(MPFS) in the reservoir area of Three-Gorge is constituted by water source forest, soil conservation forest, protection against wind and sand drifting forest, farmland protection forest, protection forest for riverside, protection forest for roades, the forest for scenery and housing. The overall arrangements of multi-functional protection forest system abide by seven principles: First to suit the site condition and the social economical requirements as to generate the ecological functions of conserving water and soil and improving the environment; Second to arrange different types of protection forests according to the protective objectives and possible nature disasters; Third to exploit the nature resources effectively and reasonablely for sustainable development of the reservoir area economy; Fourth to combine engineering and biological measures in MPFS construction. Fifth to combine ecological and economic benefits and combine short and long benefits. Sixth to integrate trees, bushes and grasses in selection of species and integrate net, belt and patch in arrangement of forest types; Seventh to optimize the structure of protection forest system in the Three-Gorge reservoir area of the Yangtze River mainly with protection forest and supplemented with other kinds of forests.

三峡库区多功能防护林体系主要由水源涵养林、水土保持林、防风固沙林、农田防护林、护岸护滩林、道路防护林及四旁植树等林种构成。多功能防护林布局一是要遵循不同地貌部位的立地条件和社会经济发展需求,最大限度地发挥多功能防护林涵养水源、保持土壤、改善环境等生态功能;二是根据防护对象及可能发生的自然灾害,因地制宜、因害设防布设不同的防护林林种;三是以保障库区的可持续发展为原则,使区域内的自然资源最有效、最合理地得以利用;四是在多功能防护林体系建设中,工程措施与生物措施相结合;五是生态效益与经济效益相结合,当前利益与长远利益相结合;六是在树种选择上实行乔、灌、草相结合。林种配置上,网、带、片相结合;七是以防护林为主,多林种协调发展,使三峡库区防护林体系结构整体优化。

The grow of Pinus Sulvestris var.mongolica in Minqin area indicated: it adapt to the climate enviroment in arid area and have strong resistance. Its drought resistance and heat resistance is stronger than that of Populus gansuensis. Meanwhile, it grow fast, have high survival rate, and the grow speed is more than 5 evergreen tree in the locality. As a ideal kind of tree for farmland protection forest, Pinus sulvestris var. mongolica have stable and lasting protection effects.

樟子松在民勤地区的生长表现表明 :樟子松能适应干旱区的气候环境 ,具有较强的抗逆性 ,其抗旱性和抗热性强于当地的防护林树种二白杨 ,且生长快 ,成活率高 ,生长速度大于当地的 5种常绿树种 (油松、青海云杉、刺柏、侧柏和杜松 ) ;樟子松作为农田防护林树种 ,具有稳定、持久的防护作用 ,是更新农田防护林比较理想的树种之一
