Based on the analysis of GIS and WASP5, theintegration of the spatial modeling function of GIS with water qualitymodel was proposed and implemented. It shows that the higherefficiency and accuracy of the integration model are achieved, and itscapability to assist water quality mangement will be greatlyenhanced.Key words: `WASP5 ( water quality analysis simulation programmodeling system) ; GIS; integration model; MiyunReservoir ` `1V1925 M, StreeterPhelpsBOD-DO£É [ ,£ÉÐ $ùî¨ùîñZëû¤v?Z b ^20W@70M}Ï ù[ª,4 M¥8£É ,ñ̨B"±sZñ,÷¹%Á¹íê þ £8Ï¥{MÄ b®ÅSSEÌ ] ßNÏ 7?»¹¥WASP "d^}V¥ B b ÏWASP5^ Kñ' bÐ üÉ¿´9Ø, 5 Ø»¹ a E²TVC# bWs ? ïµK,¹4Ú£É ¥ç© a E ? ï#^¨,C£É й Ø"d(GIS)/"î¥ t][ 1, 2] b 7?V¥ÓDÏ,ÎÀµ?C æ¨GIS¥ bWy ÿ ? <Ä£ o£É ¥¡ b[á £ o£É Eùî¹ è,ùîGISÐ£É WASP5¥ÿ ?"î,iy ëGIS <Ä¥£ o£É E"î "d b1 GIS与WASP5模型的集成1.1 `WASP5£É YVá £ oë"¥£ÉÙ5ê ÷ f ¥s,ô £É5 Ø1 p,ʨWASP5 Eá £ o£É¥H bMÄ[ 3] bWASP5 "d^Bñ¨¿ E¹V£Ïê þMÄ¥Y¨¥ O,ñ V¨¿B» a=» Ø»¥£É EÙ5 bñ^¹sý aµ{ a£ o a@ a gZ£×¥B"£ÉÙ57!9¥îÿ¥ QT bWASP5 ùî¥Ù5 BOD aDOî ïÐ a!þ/¶!Ä aµýÄÐîsM© bN S$<W¹¨¿ç©£É1 ¦¹ê ¥Q[ 4] bWASP5 ³1£/¹© Ø» bW+TÚ%¥í b Â1É£8¥£î ïÐ E,5n51ô £î ïÐ+Ä|£8ÀĹB"Mº õ¤¥£8²Ä(Junction) {¡(Channel),i9Ø£8²Ä¥£ëë a£¸Úñ a£ëëÛ£hMÄ¥MÄq,[#9ØÄñ {¡¥É a z a£ ïöå {¡' a {¡Z_ aÄñ {¡¥ zÛ£hMÄ¥MÄq© b Â1É£8¥£É E,5n51|L=£8ÀĹB"Mº1 ó¥s u(Segment),i9ØÄñs u¥£88 aM#s uW¥+ Ö[#s uW éëë© b ÂTæ¨GIS¥ bWs bWy ÿ ?,ü V[ aL®¹ |t bW+ b1. 2 `GIS o¥y ëGIS o bW o os, Ï bW oµ3ùî u = bWUS ¥5 Ø, oµ3¿òñ bWÊÂ¥ ¥5 Ø b1. 2.1 基本图件和数据的收集'mq ¥l"^GIS¨¥$,l"¥'mq : 1null 50 000¥á £ o o u¹m a1null 95 000á E¹m a1null 200 000@×¹m;l"¥' :á £ o¥£Ê Æ@ a@¥@ a£ o¥£ÉS© a¦@dÄ÷µ a©Q!ȵ [# ` © b1. 2.2 基本图件的数字化æ¨ARC/INFO"d ýT_î£ oo u¹má E¹m¥3ÄýT, æ¨Mapinfo"d ±î@×¹m¥3Ä, ª | йARC/INFOArcview¥ìT b1. 2.3 多源数据的转换l"¥' ìTòM],µ¥^dBASE¥* . dbfìT,µ¥^Excel¥* . xlsìT,µ¥^Lotus 123¥* . wk3ìT,9µ¥^È0Óq b]ìT¥ iGIS o -1Éç) Ø,) ØVñ Âm1îU bm1 ` Ð@ñm1.3 ` æ¨GIS"d3î ³1¥ 1.3. 1 库区的数字高程模型ô XÜ3Ä¥£ o o uÈ0¹m GIS¦û/T¥ bWÀÄm(m2 am3), æ¨ARC/INFO¥TIN v,y ëá £ o o u# òs u¥3Úñ (DEM ), Âm4îU bDEM ^ |WASP5 î³ t1o ¥$ bm2 `á £ o£î ïЩìÀÄmm3 `á £ o£É Es uÀÄmm4 `á £ o o u3Úñ (DEM)1.3. 2 空间测量æ¨ARC/INFO"d, V[9Ø î³¥ bW¹ :126 b¿vÐÐ(1 SÐñ) 2001, 41(8)1)s uVë o¸ëARC/INFO¥ Es uCoverage4£ oÄñs u H¥ë; æ¨TIN v3î¥su H¥3Úñ V[9ؾs u o¸ë b2)<° éëë¿s uW¥@!þÉM¥9Ø,ÄM#s uW¥<° éëë^ñ×1¥ bARCÏ¥PROFILE 7 Vô Äñ+çs u¥H¸¶9Ø<° éëë b3) o¸ Ü ( áARC/INFO4¥SLOPEÿ ?
