The ecosystem service functions of gansu is analyzed from six facts, such as grassplot ecosystem, forest ecosystem, watershed ecosystem, farmland ecosystem, desertification ecosystem and city ecosystem. this thesis simulates a latent ecosystem using vegetation type map to explain preferably how landscape pattern impacts the service function of ecosystem. the unit price of every service function is known by annual average value schedule of global ecosystem service function
為了更好地說明景觀格局變化對生態系統服務功能的影響，通過植被類型圖模擬了潛在生態系統，根據全球生態系統服務功能的年平均價值一覽表查得各服務功能單價值，將其服務功能價值進行計算並與現實生態系統服務功能價值進行比較得出：由於現實生態系統人為的干擾作用，使得生態系統服務功能價值降低了1022 . 85 10 ~ 6美元。 -
Also, through the spectral analysis in digital image processing, methods of geometric correction and accuracy analysis, strengthening of information and extraction of the feature information of emerging of ratio and information ; the extraction of species and division into sub - compartment by using multi - supplementary information sources " ; and from the identification ability of a compartment, division into sub - compartments, land type and species and the ability of accuracy of geomatric correction and map - drawing ; they can be used as the comprehensive assessment of the ability of landscape planning and many other aspects, and determine the adaptiue faculty of different information sources in the forest management inventory
經過數字圖像的光譜分析、多種方法的幾何校正及精度分析、信息增強、比值及信息融合等多重技術進行特徵信息的提取，並應用dem 、林相圖和地形圖等多種輔助信息源，提取樹種、小班區劃等信息，提高了林班區劃、小班區劃、地類和樹種識別的能力與幾何校正精度、制圖能力，可用於風景區劃等方面進行綜合評價，確定不同信息源在森林資源二類清查中的適用性能力。 -
Ecological features, function indicators and social - human impact together constitute the fundermental system of regional ecosystem health assessment. haxi forestry center is located in tianzhu of gansu province. in view of the natural conditions, land use type and forest map, we classify the research area into 15 landscape types
甘肅天祝縣哈溪林區位於祁連山東段，依據哈溪林區的自然條件、土地類型和林相圖，將研究區劃分為苗圃，未成林地，宜林地，農田，牧草地，荒地，青海雲杉林，祁連圓柏，針葉混交林，楊類闊葉林，紅樺、榆、山楊硬闊林，針闊混交林、灌木林、疏林地和闊葉混交林等15種景觀類型。 -
A preliminary study on the species composition, ecological characteristics and present distribution of vegetations in mengyang area, the largest part of xishuangbanna nature reserve, shows that there are 7 vegetation types, 15 formations, 24 community types in this area. the vegetation map was made by using gis software ( arc / info ), and the area and distribution pattern of each community was obtained. the subtropical monsoon evergreen broad leaved forest occupies the largest part, with an area of 41. 26 % of the whole, and the tropical rain forest occupies less than 10 % of the whole area. according to the topography, altitude, climate characters and present distribution of the vegetation, and based on the landscape type map, an original vegetation map under natural conditions was obtained, which could provid a theory for the vegetation restoration, especially for the tropical rain forest and its habitat, and for the development of the nature reserve
對西雙版納勐養自然保護區植被的類型進行了劃分，包括人工和自然群落，共有7個大類、 15個群系、 24個群落類型分佈.對每個類型的主要組成種類、生態特徵和分佈現狀進行了初步研究.利用地理信息系統軟體制取植被圖並獲得了各種植被類型的分佈面積和分佈格局特徵，這一地區亞熱帶季風常綠闊葉林的分佈面積和所佔比例最大，達總面積的41 . 26 % ;而熱帶雨林面積不超過總面積的10 % .依據地形、海拔、氣候和現狀植被分佈的規律，在獲得景觀類型圖的基礎上，得到了可以反映這一地區在完全自然條件下植被可能分佈的狀況的還原植被圖，為保護區的發展和植被的恢復提供了理論依據。
