The wild-fruit forests in Yili Valley occupy an area of 11330 hm2. which takes 89.5% of the total area of wild-fruit forests in Xinjiang. The formation characteristics and taxonomic classification of the soil under the wild-fruit forests are studied in the paper.The results are as follows:(1) The soil under the wild-fruit forests in Yili Valley distributes over the gentle slopes and valleys between 1100 and 1700 m a.s.l. The mean annual air temperature is 7℃, annual precipitation is 550-750...

The formation characteristics and taxonomic classification of the soil under the wild-fruit forests are studied in the paper.The results are as follows:(1) The soil under the wild-fruit forests in Yili Valley distributes over the gentle slopes and valleys between 1100 and 1700 m a.s.l. The mean annual air temperature is 7℃, annual precipitation is 550-750 mm, aridity is 1.85, and mother soil is loess-like material. (2) HA / HF is 1.05-5.75, E4 value is 1.42-2.50. The sequence of E4 value is: the soil under wild apple forests > that under wild apricot forests > that under wild walnut forests. (3) The iso-humic property, Rh is 0.32-0.39.(4) The clayization rate is 1.02-2.10, belongs to secondary clayization.(5) The calcic phenomenon, CaO bio-returning rate is 264-570.(6) The sequence of Ba value is: the soil under wild apple forests > that under wild walnut forests > that under wild apricot forests.(7) The clay minerals main1y include illite, montmorillonite and vermicutite.(8) The classiflcation of soi1 under wild-fruit forests include soil orders, soil sub-orders, soil groups, and soil sub-groups.

本文对伊犁谷地野果林下土壤的形成特点进行了研究,在此基础上,根据《中国土壤系统分类(修订方案)》[1]探讨了研究剖面在土壤系统分类中的地位和归属.

In this paper, the genetic features of the forest soils in Xinjiang are researched, and the categories of ten soil profiles in the systematic classification are discussed based on the "Chinese Systematic Classification of Soils (Revisal Proposal)". The features of the forest soils in Xin- Jiang are as follows: organic carbon is 20. 0 - 77. 6g/kg, thickness of humic hirizon 31 - 82cm, most of the base saturation 61. 2 % -96. 3 %, and there is a mollic epipedon.

In this paper, the genetic features of the forest soils in Xinjiang are researched, and the categories of ten soil profiles in the systematic classification are discussed based on the "Chinese Systematic Classification of Soils (Revisal Proposal)". The features of the forest soils in Xin- Jiang are as follows: organic carbon is 20. 0 - 77. 6g/kg, thickness of humic hirizon 31 - 82cm, most of the base saturation 61. 2 % -96. 3 %, and there is a mollic epipedon. The base saturation of partial alpine brown soil is 47. 6 %, and there is an unbric epipedon. HA/ HF and E_4 of wild fruit forest soil and gray-brown forest soil are 1. 05 - 1. 87 and 1. 60 - 2. 56 respectively, 'and that of alpine brown soil, gray-black soil and tuggic soil are 0. 46 - 0. 93 and 0. 72 - 1. 44 respectively. Rh of the wild-fruit forest soil with an isohumic property in Yili Vally is 0. 39. Caco3 in gray-brown soil and wild-fruit forest soil is 164. 4 - 202. 1g/kg, its thickness is 25- 31cm. Total salt in tuggic soil(15 cm thick) is 67. 3g/kg. Clay ratio of the most soils is 1. 20- 1. 69, Be thickness≥18cm, and there is an argillaceous horizon. Clay ratio of some soils is less than 1. 20, and there is a cambium. The eluvial degree is: alpine brown soil> gray-black soil > wild-fruit forest soil > gray-brown soil > tuggic soil. The total chemical compositions of clay grains (< 0. 002 mm) in alpine brown soil and gray-black soil are 1. 20 - 1. 17 and 1. 24 - 1. 18 respectively, which show that R_2O3 has a movement. Some clay minerals are contained in the soils. alpine brown soil contains montmoril- Ionite, illite and vermiculite, gray-black soil contains montmorillonite and illite, wild-forest soil and gray - brown soil contain illite and montmorillonite. The results show that the 10 soil pro- files belong to 4 orders, 7 suborders, 9 groups and 9 subgroups respectively.

本文对新疆森林土壤的形成特征进行了研究,根据《中国土壤系统分类(修订方案》探讨了10个剖面在土壤系统分类中的归属问题。

According to 31 selected eco -economic indexes , taking administrative county (district)as the unit ,the paper divides the Three Gorges reservoir area into 4 agroecological -economic regions by the fuzzy cluster analysis method of ISOTATA , that is, Ⅰthe vegetable -tourism-flower-animal husbandry-processing eco-economic region in the hilly area of outskirts of the main city proper ,Ⅱthe grain-economic crop-fruit- animal husbandry- processing eco-economic region in the hilly and low mountainous areas between...

According to 31 selected eco -economic indexes , taking administrative county (district)as the unit ,the paper divides the Three Gorges reservoir area into 4 agroecological -economic regions by the fuzzy cluster analysis method of ISOTATA , that is, Ⅰthe vegetable -tourism-flower-animal husbandry-processing eco-economic region in the hilly area of outskirts of the main city proper ,Ⅱthe grain-economic crop-fruit- animal husbandry- processing eco-economic region in the hilly and low mountainous areas between Jiangjin City and Wanzhou District, Ⅲ the fruit-forest- grain- animal husbandry-speciality eco-economic region in the middle and low mountainous areas between Wulong County and Zilui County, Ⅳ the forest- fruit- animal husbandry- grain eco-economic region in the low and middle mountainous and hilly areas of Xingshan County and Yichang County. Through analyzing the eco -economic characteristics of each region, it puts forward their eco -economic developing direction and the strategies of ecological environment protection. Thus it can provide theoretical basis for agricultural sustainable development and ecological environment protection in the Three Gorges reservoir rea.

选取 31个生态经济指标 ,以行政县 (区 )为单元 ,采用 ISOTATA模糊聚类分析方法 ,把三峡库区分为 4个农业生态经济区 ,即 主城区城郊丘陵菜旅花牧加生态经济区、 江万丘陵低山粮经果牧加生态经济区、 武秭中山低山果林粮牧特生态经济区、 兴宜低山中山丘陵林果牧粮生态经济区。通过对各区生态经济特征的分析 ,提出了其生态经济的发展方向和生态环境保护的策略 ,可为三峡库区农业可持续发展和生态环境保护提供理论依据。
