Ziwa la mchanga wa mchanga ni ufuo wa mchanga ambao huunda mipasuko kutokana na upepo.、Haya ni vinamasi vya maji baridi ambavyo hutengenezwa kiasili mito inapotiririka hadi kwenye mabonde (Sagata, Wilaya ya Niigata, n.k.)。Mchanga wa chini ya maji huvimba kama tuta kwa sababu ya mikondo ya bahari na mawimbi, na kuziba njia ya kutoka.、(Imeundwa tofauti na maziwa ya maji ya chumvi kama vile Ziwa Saroma na Hachirogata)。Ziwa la mchanga lenyewe ni chombo cha thamani ambacho kinapotea kote ulimwenguni.、Kuunda mazingira yenye thamani ya kibayolojia。
Sand dune lake is a natural freshwater pond in a sandhill. It was shaped by wind. The wind had been carring sand and formed ups and downs, and then water stream into hollow places. It is not only very valuable existence itself in the world but also it gives important environment for biodeversity that’s being lost.
Katika Kijiji cha Higashidori、Kuna "maziwa ya mchanga" mengi makubwa na madogo (mabwawa 13 yanayoitwa peke yake).。Kijiji cha Higashidori, Matuta ya Mchanga ya Sarugamori, na Ardhioevu ya Nyuma zimechaguliwa kuwa mojawapo ya ardhi oevu 500 muhimu za Japani (kwa kweli, inaweza kusemwa kwamba sehemu kubwa ya Rasi ya Shimokita imechaguliwa kwa njia hii).。Tumbili hili la mchanga wa msitu wa tumbili (upana 1-2 km)、"Matuta ya Mchanga ya Shimokita" ni mchanganyiko wa matuta ya mchanga (jumla ya urefu wa kilomita 17) na matuta ya mchanga ambayo huenda ndani kidogo ya nchi.、Ingawa inajulikana kidogo, kwa kweli ndiyo matuta makubwa zaidi ya mchanga nchini Japani.。Sababu haijulikani ni、Misitu ya ulinzi wa upepo na mchanga huzunguka matuta ya mchanga.、Mambo ambayo ni vigumu kwa watu kuona、Wengi wao hutumiwa na Wizara ya Ulinzi na wengine kwa maeneo ya mtihani wa ballistic, nk.、Hii ni kwa sababu ni marufuku kuingia.。
Kuna wengi maziwa Dune katika Higashi-Dori kijiji. Aitwaye maziwa ni kima cha chini cha 13s. Sandhill Salugamori (1~ 2 km upana, 17 km urefu) include the rear wetland in this village has selected one of 500 of the important wetland of Japan (Wengi kweli ya Shimokita peninsula ni kuchaguliwa pia). Additionaly, Shimokita Sandhill (includ this Salugamori sandhill with the next ones) is really the biggest one in Japan. However almost all japanese don’t know of it. One of the reason is that this place is hidden from the roads by pine grove for protect the wind and the sand. The other one, here is off limited, because this ares has been useing for test site of trajectory of Ministry of Defence (MD).
Ziwa lenyewe liko nje ya eneo la Wizara ya Ulinzi.、Baadhi yake inaonekana kutumika kwa madhumuni ya uvuvi pia.。Hata hivyo, misitu ya misonobari inayotumika kulinda upepo na mchanga pia imeongezeka zaidi.、Barabara nyingi zinazoelekea kwenye kinamasi zinatoweka.。Kupungua kwa idadi ya watu na kuzeeka kunaendelea hapa pia.、Hakuna utafiti wa kitaaluma unaofanywa kwa sasa.。
These are out of the area of MD. A few lakes of it look as useing fishery sometimes but not often. Most of the roads to go there is being lost by growing thickly weeds and pine grove. Creasing depopulation and ageing there. Academic reserch kusimamishwa sasa.
Picha ni kutoka juu hadi chini (zimepangwa kutoka kaskazini hadi kusini)、Onuma、Sakyo Marsh、Aranuma。Ukubwa na kina hutofautiana kidogo, lakini wote wako katika hali yao ya asili.。Onuma ni kamba mkubwa、Sakyo-numa ni maarufu kwa Aegagropila Linnaei.、Nini kinatokea sasa kama hakuna utafiti uliofanywa?。Arauma ina kina cha 1-2m.、Brasenia schreberi inavunwa.。
Picha:(juu ya) O-. Small mto prawn maisha katika. (midlle) Sakyo-numa. Sakyo-numa is famous for “Hime-malimo” (ndogo moss mpira), lakini ni jinsi gani sasa? (chini) An old woman was picking “Juni-alipokea” (ngao maji) from the water at lake Ala-numa. ※ Numa njia ziwa au bwawa. Wote wa maziwa ni Dune Hali.
