【摘要】：遼寧沿海區(qū)域有多條河流注入黃、渤二海，滋育了類型多樣的濱海濕地資源。長期以來，這些濕地資源不僅維持了區(qū)域環(huán)境的生態(tài)平衡，同時(shí)在遼寧省海洋產(chǎn)業(yè)結(jié)構(gòu)、環(huán)渤海區(qū)域海洋經(jīng)濟(jì)發(fā)展中占有極為重要的位置。本文以遼寧沿海經(jīng)濟(jì)帶2010年夏季相Landsat7-ETM影像數(shù)據(jù)、行政區(qū)劃數(shù)據(jù)、五大工業(yè)園區(qū)分布數(shù)據(jù)、自然保護(hù)區(qū)分布數(shù)據(jù)為基礎(chǔ)數(shù)據(jù)源，，利用Geodatabase數(shù)據(jù)模型，構(gòu)建遼寧沿海經(jīng)濟(jì)帶濕地資源信息系統(tǒng)數(shù)據(jù)庫；采用景觀相對(duì)豐富度指數(shù)和景觀多樣性指數(shù)，分析了2010年遼寧沿海經(jīng)濟(jì)帶濕地資源景觀空間分異特征；基于遼寧沿海經(jīng)濟(jì)帶2007年和2010年的濕地資源數(shù)據(jù)，揭示了遼寧沿海經(jīng)濟(jì)帶濕地景觀格局的動(dòng)態(tài)變化特征。主要研究結(jié)果為： （1）遼寧沿海經(jīng)濟(jì)帶濕地資源信息系統(tǒng)數(shù)據(jù)庫由空間數(shù)據(jù)庫和屬性數(shù)據(jù)庫構(gòu)成，空間數(shù)據(jù)庫數(shù)據(jù)包括遼寧省行政區(qū)劃、遼寧沿海經(jīng)濟(jì)帶縣級(jí)行政區(qū)劃、遼寧沿海經(jīng)濟(jì)帶2007年、2010年濕地、非濕地資源現(xiàn)狀分布、遼寧沿海經(jīng)濟(jì)帶淺海水域、遼寧沿海經(jīng)濟(jì)帶濕地自然保護(hù)區(qū)、遼寧沿海經(jīng)濟(jì)帶五大工業(yè)園區(qū)；屬性數(shù)據(jù)庫包括遼寧沿海經(jīng)濟(jì)帶行政區(qū)屬性表、遼寧沿海經(jīng)濟(jì)帶濕地資源屬性表、遼寧沿海經(jīng)濟(jì)帶非濕地資源屬性表、遼寧沿海經(jīng)濟(jì)帶濕地自然保護(hù)區(qū)屬性表、遼寧沿海經(jīng)濟(jì)帶五大工業(yè)園區(qū)屬性表。 （2）2010年遼寧沿海經(jīng)濟(jì)帶濕地資源總面積為719955.58hm~2。從濕地類型看，平原水田面積最大，為400815.29hm~2，占遼寧沿海經(jīng)濟(jì)帶濕地總面積的55.67%，鹽堿地、鹽田和山地水田較小，分別為572.15hm~2、302.64hm~2和229.02hm~2，占總面積的0.08%、0.04%和0.03%；從濕地分布區(qū)域看，盤錦市濕地面積最大，為267542.95hm~2，占遼寧沿海經(jīng)濟(jì)帶濕地總面積的37.16%，葫蘆島市最小，為35233.3hm~2，占總面積的4.89%；從濕地景觀相對(duì)豐富度指數(shù)看，丹東市最大，為0.92，表明丹東市濕地資源類型最多，濕地景觀最豐富，盤錦市最小，為0.58，表明盤錦市濕地資源類型最少，濕地景觀較為單一；從濕地景觀多樣性指數(shù)看，葫蘆島市最大，為1.63，表明葫蘆島市濕地景觀分布較均勻，營口市最小，為0.47，表明營口市濕地景觀分布不均勻。 （3）2007-2010年間，葫蘆島市濕地景觀相對(duì)豐富度指數(shù)變化最大，變化幅度為-25.56%，大連市變化幅度最小，為3.75%；丹東市濕地景觀多樣性指數(shù)變化最大，變化幅度為-24.84%，葫蘆島市變化最小，為-0.61%；大連市是遼寧沿海經(jīng)濟(jì)帶唯一一個(gè)濕地景觀相對(duì)豐富度指數(shù)和多樣性指數(shù)均增加的城市，表明大連市濕地景觀種類有所增加，同時(shí)濕地景觀結(jié)構(gòu)復(fù)雜性也有所增加，濕地景觀分布趨于均勻。
[Abstract]:Many rivers in the coastal area of Liaoning are injected into Yellow River and Bohai two sea, which nurture various types of coastal wetland resources. For a long time, these wetland resources not only maintain the ecological balance of the regional environment, but also occupy a very important position in the marine industrial structure of Liaoning province and the development of the marine economy around Bohai region. This article is based on the coastal economy of Liaoning. With the 2010 summer Landsat7-ETM image data, the administrative division data, the five industrial park distribution data, the natural reserve distribution data as the basic data source, the wetland resources information system database of Liaoning coastal economic zone is constructed by using the Geodatabase data model, and the landscape relative richness index and the landscape diversity index are used to analyze the landscape diversity index. The spatial differentiation characteristics of wetland resources in Liaoning coastal economic belt in 2010 are divided. Based on the wetland resource data of Liaoning coastal economic belt in 2007 and 2010, the dynamic characteristics of wetland landscape pattern in Liaoning coastal economic zone are revealed. The main research results are as follows:
(1) the database of wetland resources information system of Liaoning coastal economic belt is composed of spatial database and attribute database. The spatial database data include the administrative division of Liaoning Province, the county administrative division of the coastal economic belt of Liaoning, the coastal economic belt of Liaoning in 2007, the wetland in 2010, the current distribution of non wetland resources, the shallow sea waters of the coastal economic belt of Liaoning and Liao. Ningxia coastal economic belt Wetland Nature Reserve, Liaoning coastal economic zone five industrial parks; attribute database including Liaoning Coastal Economic Zone Administrative Area property table, Liaoning coastal economic zone wetland resource attribute table, Liaoning coastal economic zone non wetland resource attribute table, Liaoning coastal economic zone Wetland Nature Reserve attribute table, Liaoning coastal channel Five industrial park properties table.
(2) in 2010, the total area of wetland resources in Liaoning coastal economic zone was 719955.58hm~2. from wetland type. The area of plain paddy field was the largest, 400815.29hm~2, accounting for 55.67% of the total wetland area in the coastal economic zone of Liaoning, saline alkali land, salt field and mountain paddy field, respectively 572.15hm~ 2302.64hm~2 and 229.02hm~2, accounting for 0.08%, 0.04% and 0.03% of the total area. From the wetland distribution area, the largest wetland area in Panjin is 267542.95hm~2, which accounts for 37.16% of the total wetland area in Liaoning coastal economic zone, the smallest in Huludao, 35233.3hm~2, accounting for 4.89% of the total area. From the relative richness index of wetland landscape, the largest of Dandong is 0.92, indicating that the wetland resources in Dandong are the most abundant and the wetland landscape is the most abundant. The smallest in Panjin is 0.58, which shows that the wetland resources in Panjin are the least and the wetland landscape is relatively single. From the wetland landscape diversity index, the largest in Huludao is 1.63, indicating that the distribution of the wetland landscape in Huludao is more uniform and the smallest in Yingkou, 0.47, indicating that the wetland landscape in Yingkou is not evenly distributed.
(3) in 2007-2010 years, the relative richness index of wetland landscape in Huludao was the biggest change, the change range was -25.56%, the change range of Dalian city was the smallest, 3.75%. The wetland landscape diversity index in Dandong was the largest, the change range was -24.84%, the change of Huludao city was -0.61%, Dalian was the only wetland in Liaoning coastal economic zone. The urban landscape with the increase of the landscape relative richness index and diversity index shows that the wetland landscape in Dalian has increased, and the complexity of wetland landscape structure is also increasing, and the distribution of wetland landscape tends to be uniform.
