Yog lawm. Ib qho kev txhais ntawm kev sib haum xeeb yog tias koj tuaj yeem nqa ib qho puab thiab qhov chaw nws nyob saum lwm tus puab , thiab muaj ib qho kev sib tw. Yog li ntawd lawv muaj tib cheeb tsam.
Yog li ntawd, cov nuj nqis sib koom ua ke puas muaj ib cheeb tsam?
Cov duab sib dhos muaj sib npaug thaj chaw . Thaum peb thawj zaug nkag rau lub tswv yim ntawm kev sib haum xeeb polygons (feem ntau daim duab peb sab ) hauv tsev kawm ntawv, peb feem ntau txhais cov duab zoo sib xws raws li " cov duab uas muaj ib yam puab thiab loj".
Ib yam li ntawd, qhov txawv ntawm qhov sib txuam thiab cov duab zoo sib xws yog dab tsi? Cov duab sib xws yog tib yam puab thiab loj. Cov duab zoo sib xws yog tib yam puab , tab sis tsis tas qhov loj me. Nco ntsoov tias yog ob cov duab yog kev sib haum xeeb , ces lawv kuj yog zoo sib xws , tab sis tsis vice-versa.
Ua raws li qhov no hauv kev txiav txim siab, cov duab sib xyaw ua ke puas zoo sib xws?
Nws yog geometry sib npaug ntawm 'sib npaug'. Cov duab sib xws muaj tib yam qhov loj, tib yam kaum sab xis, tib yam sab thiab tib lub cev . Cov duab zoo sib xws muaj tib yam cov ces kaum uas txhais tau tias lawv muaj tib cov duab , tab sis lawv txawv qhov loj.
Yuav ua li cas koj thiaj paub tias ib yam dab tsi sib haum?
Ob polygons yog concru yog lawv yog cov loj thiab zoo tib yam - uas yog, yog lawv cov ces kaum thiab sab sib npaug. Txav koj tus cursor nas hla qhov chaw ntawm txhua daim duab ntawm sab laug kom pom qhov sib thooj ntawm qhov kev sib haum xeeb daim duab ntawm sab xis.

Hom nroj tsuag twg muaj nyob rau hauv cheeb tsam arid?
Cov cheeb tsam arid (arid Performance index 0.03-0.20) yog tus cwj pwm los ntawm pastoralism thiab tsis muaj kev ua liaj ua teb tshwj tsis yog muaj dej.

Lub cheeb tsam dej hiav txwv twg muaj biodiversity loj tshaj plaws thiab lub neej dej hiav txwv tshaj plaws?
Epipelagic cheeb tsam nthuav tawm ntawm qhov chaw mus txog 200m nqes. Nws tau txais ntau lub hnub ci thiab yog li muaj cov biodiversity tshaj plaws nyob rau hauv dej hiav txwv. Nws tseem hu ua thaj tsam twilight vim tias lub teeb txwv tsis pub muaj peev xwm lim tau los ntawm cov dej no
Lub cheeb tsam twg muaj ntau haiv neeg?
Ntau hom kev sib txawv yog qhov loj tshaj plaws nyob rau hauv lub tropics, tshwj xeeb tshaj yog nyob rau hauv hav zoov kub thiab coral reefs. Lub Amazon phiab hauv South America muaj thaj tsam loj tshaj plaws ntawm hav zoov hav zoov. Sab qab teb sab hnub poob Pacific muaj qhov sib txawv loj tshaj plaws ntawm coral reef hom
Puas yog daim duab peb sab congruent muaj tib lub perimeter?
Yog tias ob daim duab peb sab sib npaug, ces txhua feem ntawm daim duab peb sab (sab los yog lub kaum sab xis) yog congruent rau qhov sib thooj hauv lwm daim duab peb sab. Ntxiv rau ob sab thiab cov ces kaum, tag nrho lwm yam khoom ntawm daim duab peb sab yog tib yam, xws li thaj tsam, ib puag ncig, qhov chaw ntawm cov chaw, lub voj voog thiab lwm yam
