Secondly, based on the microbeam analytical technique, on the one hand, through investigating the characteristic of major elements in the mantle minerals the author acquired the static information from mantle ; on the other hand, through multi - point analysis of a part of the minerals from mantle, the auther got dynamic information from mantle. finally, generalizating the fruits of this study and predecessors, the autor holds that the constituents of lithospheric mantle possibly includes spinel lherzolites, clinopyroxenites, websterite, dunite, harzburgites, garnet lherzite, phlogopite lherzite, eclogites, clinopyroxene megacrysts ; compared with east china and north china platform, the research field mantle shows the characteristics of higher degree of partial melting processes and more depleted mantle ; the. upper mantle beneath north hetian area is heterogeneous, with a tendency of deficit in a12o3 and lree from kaliyang in west hetian to the river basin of kalakshi river and yulongkashi river ; the subduction of the crust beneath north hetian has ever occurred in geological history and caused the mixing of mantle - crust ; the depth of the origination of basaltic magmas beneath north hetian exceeds 73km ; the thickness of the lithosphere beneath the research area amounts to 204. 9km ; the mantle beneath north hetian has geological condtions for forming diamond deposits
最後,綜合本區幔源礦物和地幔巖石的特徵以及地球物理資料,得出如下結論:本區上地幔的物質組成有尖晶石二輝橄欖巖、二輝巖、單斜輝石巖、純橄欖巖、方輝橄欖巖、石榴石二輝橄欖巖、金雲母二輝橄欖巖、榴輝巖;與中國東部以及華
北地臺上地幔相比,研究區上地幔具有富集主元素中相容元素和虧損其中的不相容元素的特徵,局部熔融程度較高;上地幔存在橫向和縱向的不均一性,從西部的克里陽到喀拉喀什河和玉龍喀什河流域, al和lree富集程度呈下降趨
勢,不同來源的相同礦物中主元素的含量差異較大;地質歷史時期這里可能發生過地殼俯沖並產生殼幔混合作用;玄武巖漿的起源深度73km ;從幔源重砂礦物的溫壓估算結果,可以推斷出巖石圈厚度可達204 . 9km ;綜合巖石圈物質組成特徵、巖石圈熱狀態、地幔溫壓狀態、氧逸度以及幔源巖石和幔源礦物的化學成分,認為研究區具備了金剛石成礦地幔地質條件。

Based on an analysis of the history and present status of the farmland - pastoral ecotone in the northern part of china, a new point of view was proposed in this paper for the construction of eco - environmental systems, namely, the industrial structure has to be modified so as to make a functional integration between different parts of the whole system : to give priority to a combination between cultivated grassland and in - shed feeding of domestic animals, and at the same time, to employ a new model of animal husbandry so that the degradated natural grassland can be recovered ; to develop a new type of processing industry for agricultural and forestal products so as to create a pluralistic enterprise structure ; to make a better use of water resources by taking advantages of the abundant resources of energy and minerals, and to restrain the expansion of industries of high environmental cost ; to employ techniques of integration management and restoration ecology, and to speed up the process of woodland and grassland recovery ; to make a thorough plan for arrangements of hills, waters, roads, farmlands, forests and pastures in order to gain an integration at landscape level
摘要在簡要分析中國
北方農牧交錯帶形成歷史和現狀的基礎上,提出了
北方地區生態環境建設必須從產業結構調整出發、進行系統功能整合的思路:把人工飼草業舍飼畜牧業擺在農牧交錯帶經濟發展的優先位置,推行新型畜牧業經營管理模式,促進天然草場改良復壯;發展「綠色」農林牧產品精細加工業,建立多元化產業結構;發揮能源和礦產資源優
勢,合理利用水資源,限制以破壞環境為代價的產業的發展;推廣區域綜合治理與生態恢復技術,加大退耕還林還草的力度;山、水、路、農、林、牧統一規劃,實現生態系統在景觀水平上的整合。
