earth resources satellite 地球資源衛星。

earth satellite

Dealing with remote sensing data of different time ( 1987 , 1996 landsat tm , and 2000 china - brazil earth resource satellite ccd ) and using the gis technology , the dissertation extracts the changing information of the desertification . the dissertation makes a dynamic remote sensing analysis on the desertification of the research region , and discusses the temporal and spatial evolving law of the desertification 在技術上主要采用了1987 、 1996年的陸地衛星tm數據以及2000年中巴資源衛星1號ccd數據三個不同時相的遙感數據進行圖像處理,并利用gis較強的空間分析功能,從中提取研究區土地沙漠化的變化信息,同時與研究區的其他信息數據進行疊加分析,探討了研究區土地沙漠化的時空演化特點。

Based on field research and the dynamic analysis of remote sensing data of different time ( 1987 tm , 1996 tm and 2000 china - brazil earth resource satellite ccd ) , using multi - information of research area ( including data of geology , geography , hydrology , meteorology , economy , human culture and dem ) and existing research results , the dissertation discusses drive factors of desertification and the relationships between drive factors and desertification with the help of gis tool and some mathematical methods such as probability , statistics , curvilinear estimation , logical analysis and analytic hierarchy process 論文在對研究區土地荒漠化現狀野外調研和不同時相( 1987tm 、 1996tm和2000ccd )遙感圖像土地荒漠化信息提取和演變分析的基礎上,結合研究區已有的多元信息基礎資料及研究成果(包括地質、地理、多時期的水文氣象、經濟、人文以及dem數據等) ,運用gis強大的空間分析功能和概率統計、曲線估計、邏輯分析、主成分分析、層次分析等數學方法綜合研究了土地荒漠化與各驅動因子之間的相關關系,揭示了研究區土地荒漠化的主要驅動因素,探討了荒漠化動態演化規律。

China now has mature technologies to design and produce different types of orbital vehicles , such as scientific experimentation satellites , recoverable satellites , geostationary orbit communications satellites , and meteorological and earth resources satellites 中國現擁有研制科學實驗衛星、返回式衛星、地球靜止軌道通信衛星、氣象衛星、資源衛星等設計和制造的成熟技術。

The collaboration between china and brazil on the project of an earth resources satellite is making good progress , and the first such satellite was successfully launched by china on october 14 , 1999 中國與巴西開展的地球資源衛星合作進展順利。 1999年10月14日,中國成功地發射了第一顆中巴地球資源衛星。

The major technological index of china ' s meteorological and earth resource satellites have reached the international level of the early 1990s 中國的氣象衛星、地球資源衛星主要技術指標已達到二十世紀九十年代初期的國際水平。
