Momwe Mungachitire Kafukufuku wa Zachilengedwe mu Nkhalango Yamvula
Nkhalango zamvula ndi zina mwa zachilengedwe zovuta kwambiri padziko lapansi. Kuchuluka kwa zamoyo zawo zosiyanasiyana, kapangidwe ka zomera zambiri, komanso kuyanjana kwa mitundu yosiyanasiyana kumapangitsa kuti zikhale "malo ophunzirira zachilengedwe" ofunika kwambiri pakufufuza zachilengedwe. Komabe, kuchita kafukufuku m'nkhalango zamvula sikophweka monga kukhazikitsa zida ndi kusonkhanitsa deta. Malo ovuta, nyengo yosinthasintha mofulumira, ndi zinthu zotetezera zimafuna kukonzekera mosamala. Nkhaniyi ikufotokoza njira zothandiza pochita kafukufuku wa zachilengedwe m'nkhalango zamvula mwadongosolo komanso moyenera.
1. Dziwani zolinga ndi mafunso ofufuza
Gawo loyamba ndi kupanga zolinga zomveka bwino za kafukufuku. Kafukufuku wa zachilengedwe akhoza kuyang'ana kwambiri mitu yambiri: kapangidwe ka zomera, njira zogawa nyama, kuchuluka kwa anthu, kusinthasintha kwa zakudya, ubale pakati pa nyama ndi nyama, komanso zotsatira za kusintha kwa nyengo ndi zochita za anthu. Pangani mafunso ofufuza omwe ndi enieni, oyesedwa, komanso okhudzana ndi momwe zinthu zilili m'munda.
Mafunso a chitsanzo: Kodi kuwala kwa pansi pa nkhalango kumakhudza bwanji kukula kwa mitengo ya mbande? kapena Kodi kugawikana kwa nkhalango kumakhudza kuchuluka kwa mbalame zodya tizilombo? Mafunso amtunduwu adzakuthandizani kudziwa njira, malo, ndi mitundu ya deta yomwe mukufuna.
2. Kuphunzira mabuku ndi kusankha malo
Musanayambe ntchito yanu, chitani ndemanga ya mabuku pogwiritsa ntchito magazini, malipoti, kapena deta yam'mbuyomu yokhudzana ndi dera lofufuzira. Muyenera kumvetsetsa mtundu wa nkhalango (yoyamba, yachiwiri, dambo, mapiri), nyengo, ndi nkhani zokhudzana ndi kusungirako zachilengedwe m'deralo. Kubwerezabwereza mabuku kumathandizanso kupewa kubwerezabwereza kafukufuku wakale ndikupanga kapangidwe kolimba kwambiri.
Kusankha malo kuyenera kuganizira momwe mungafikire, chitetezo, ndi zilolezo kuchokera kwa akuluakulu aboma. Mwachitsanzo, mapaki adziko ali ndi malamulo okhwima; nkhalango zachikhalidwe zimafuna chilolezo cha anthu ammudzi. Kuphatikiza apo, onetsetsani kuti malo anu akuyimira mikhalidwe yomwe mukufuna kuphunzira, monga dera lomwe lili pafupi ndi mtsinje, phiri, kapena dera lomwe lili m'mphepete mwa nkhalango.
3. Kusamalira zilolezo zofufuzira ndi makhalidwe abwino
Kafukufuku wa nkhalango zamvula nthawi zambiri amakumana ndi nkhani zosamalira zachilengedwe komanso ufulu wa anthu ammudzi. Chifukwa chake, zilolezo ndi makhalidwe abwino ndizofunikira kwambiri. Kusunga zilolezo zolowera, zilolezo zotengera zitsanzo (ngati pakufunika), ndi zilolezo zogwiritsira ntchito zida zinazake monga ma drone kapena misampha ya kamera. Ngati kafukufukuyu akuphatikizapo nyama, tsatirani malangizo okhudza ubwino wa nyama ndikuchepetsa kusokonezeka.
Gwiritsani ntchito madera am'deralo mwachilungamo: fotokozani zolinga za kafukufuku, pezani chilolezo ngati mulowa m'malo omwe anthu amawagwiritsa ntchito kale, ndipo ngati n'kotheka, lembani alangizi am'deralo kapena othandizira m'munda. Izi sizimangothandiza pa kayendetsedwe ka zinthu, komanso zimamanga ubale wabwino komanso zimachepetsa mikangano.
4. Pangani kapangidwe ka kafukufuku ndi njira zotsanzira zitsanzo
Kapangidwe ka kafukufuku kamatsimikizira ubwino wa zotsatira zake. M'nkhalango zamvula, njira zopezera zitsanzo ziyenera kukhala zokhoza kuzindikira kusiyana kwakukulu. Njira zina zodziwika bwino ndi izi:
a. Malo obzala zomera
Pofuna kuyeza kapangidwe ka nkhalango ndi kapangidwe kake, ofufuza nthawi zambiri amapanga malo owonetsera (monga 20x20 m kapena 50x50 m). Mkati mwa malo owonetsera, mitengo yonse yokhala ndi mainchesi enaake (monga DBH ≥ 10 cm) imazindikiritsidwa ndikuyesedwa. Kuchulukana, kulamulira, zizindikiro za kusiyana, ndi biomass zimatha kuwerengedwa.
b. Transect
Ma transect a mzere kapena ma transect a lamba amagwiritsidwa ntchito pophunzira kusintha kwa anthu ammudzi motsatira njira yosinthira, mwachitsanzo kuyambira m'mphepete mwa nkhalango mpaka pakati pa nkhalango, kapena kuchokera kumadera otsika mpaka kumapiri.
c. Misampha ya makamera ndi kafukufuku wa nyama
Misampha ya makamera ndi yothandiza kwa nyama zoyamwitsa zapansi ndi mbalame zomwe zimakhala zovuta kuziona mwachindunji. Kwa mbalame za anyani kapena mbalame za m'denga, njira zowerengera mfundo kapena njira zolembera mizere nthawi zambiri zimakhala zoyenera.
d. Kusankha dothi ndi zinyalala
Kusanthula nthaka kumapereka chidziwitso pa pH, carbon, nayitrogeni, phosphorous, ndi kuchuluka kwa chinyezi. Zinyalala ndi kuwonongeka kwa nthaka zitha kuphunziridwa pogwiritsa ntchito matumba a zinyalala kuti mumvetse momwe michere imayendera.
Sankhani njira yomwe ikugwirizana ndi funso lanu lofufuza, kenako dziwani kukula kwa chitsanzo, kuchuluka kwa zomwe mwawona, ndi nthawi ya kafukufuku kuti deta ikhale yolondola.
5. Kukonzekera zida, kayendedwe ka zinthu, ndi chitetezo
Nkhalango zamvula zimakhala ndi mavuto apadera m'munda: mvula yamphamvu, mimbulu, udzudzu, malo otsetsereka, komanso chiopsezo chosochera. Chifukwa chake, kukonzekera zinthu ndikofunikira. Zipangizo zodziwika bwino zimaphatikizapo GPS, kampasi, tepi yoyezera, tepi ya mainchesi, clinometer, buku lozindikiritsa, kamera, zolembera zosalowa madzi, ndi zida zoyesera zitsanzo.
Kuti mukhale otetezeka, konzani zida zothandizira oyamba, jekete la mvula, nsapato zoyenera zakumunda, mankhwala ophera tizilombo, ndi chipangizo cholankhulirana ngati chizindikirocho chikulola. Pangani dongosolo loti mutuluke ndipo nthawi zonse muzigwira ntchito limodzi. Kudziwitsana musanapite kumunda ndikofunikira kuti mamembala onse amvetse njira zotetezera, njira, ndi maudindo awo.
6. Kusonkhanitsa deta m'munda
Posonkhanitsa deta, kusinthasintha ndikofunikira kwambiri. Gwiritsani ntchito njira zodziwika bwino: njira yoyezera kukula kwa mitengo iyenera kukhala yofanana pa malo onse; nthawi yowonera mbalame iyenera kukhala yofanana tsiku lililonse; ndipo malo osungira kamera ayenera kulembedwa mwatsatanetsatane. M'nkhalango zamvula, kusintha kwa nyengo kungakhudze zotsatira, choncho lembani mikhalidwe yachilengedwe monga kuchuluka kwa mvula, kutentha, ndi kuchuluka kwa kuwala.
Kusunga mtundu wa kuzindikira mitundu ya zomera n'kofunika kwambiri. Ngati simuli katswiri wa za ziweto, lembani zitsanzo za zomerazo ndi zithunzi ndi zolemba za mawonekedwe a zomera, kapena gwirizanani ndi akatswiri am'deralo. Pa zomera, nthawi zambiri pamachitika zitsanzo za zomera, koma ziyenera kuchitika ndi chilolezo osati mopitirira muyeso.
7. Kusamalira ndi kusanthula deta
Deta yabwino ya m'munda ikhoza kuwonongeka ngati simukuisamalira bwino. Mukabwerera kuchokera kumunda tsiku lililonse, konzani zosungira deta yanu: zithunzi, zolemba, ma GPS coordinates, ndi mafomu owonera. Gwiritsani ntchito matebulo a digito ndikuwonetsetsa kuti mayina a mafayilo ndi ofanana. Zolakwika zazing'ono, monga ma coordinates osakanikirana, zitha kuwononga kusanthula kwanu.
Kusanthula deta kumadalira cholinga. Pa zomera, mutha kuwerengera Shannon kapena Simpson index, kusanthula kapangidwe ka diameter, kapena chitsanzo cha biomass. Pa zinyama zakuthengo, mutha kugwiritsa ntchito kusanthula kuchuluka kwa zinthu, kupanga chitsanzo cha occupancy, kapena kubwezeretsanso chizindikiro. Mapulogalamu omwe amagwiritsidwa ntchito kwambiri akuphatikizapo R, QGIS pokonza mapu, ndi mapulogalamu ena owerengera ziwerengero.
8. Kutanthauzira ndi kutsimikizira zotsatira
Nkhalango zamvula zimakhala ndi kusiyana kwakukulu kwachilengedwe, kotero kutanthauzira zotsatira kuyenera kukhala kosamala. Zomwe zapezeka kuchokera pamalo amodzi sizingagwire ntchito kudera lonselo. Kambiranani zinthu zosokoneza monga kusiyanasiyana kwa kukwera kwa nthaka, kusokonezeka kwa anthu, kapena kusiyana kwa nyengo.
Ngati n'kotheka, tsimikizirani zomwe mwapeza pobwereza miyeso kapena kuziyerekeza ndi deta yakale. Njira yogwiritsira ntchito njira zambiri—monga kuphatikiza misampha ya kamera ndi kafukufuku wa njira ndi mafunso am'deralo—ingalimbikitse mfundo.
9. Lipoti la kusunga zachilengedwe, kufalitsa ndi kupereka
Gawo lomaliza ndi kulemba lipoti la kafukufuku. Fotokozani njira mwatsatanetsatane kuti kafukufukuyo athe kubwerezedwanso. Perekani zotsatira zake ndi matebulo, ma graph, ndi mamapu ogawa. Kuwonjezera pa mabuku asayansi, ganizirani zopanga chidule cha oyang'anira madera, maboma am'deralo, kapena madera am'deralo m'chinenero chosavuta kumva.
Kafukufuku wa zachilengedwe m'nkhalango zamvula ayenera kukhala ndi zotsatira zenizeni pa kusungirako zachilengedwe: mwachitsanzo, kupereka malingaliro okhudza madera oteteza nyama zakuthengo, njira zobwezeretsa, kapena kuyang'anira mitundu ya zinyama. Ofufuza ayeneranso kuonetsetsa kuti ntchito zofufuzira sizisiya zotsatirapo zoipa monga zinyalala kapena kuwonongeka kwa zomera.
Kutseka
Kuchita kafukufuku wa zachilengedwe m'nkhalango zamvula kumafuna kuphatikiza kwa sayansi yokhwima komanso kukonzekera bwino malo. Kuyambira kupanga mafunso ndikupanga mapangidwe a zitsanzo, kupeza zilolezo, ndi kuyang'anira deta, chilichonse chiyenera kuchitika mwanzeru. Ndi njira yoyenera, kafukufuku wanu angathandize kumvetsetsa momwe zachilengedwe za nkhalango zamvula zimagwirira ntchito komanso kuthandizira zoyesayesa zosungira zachilengedwe m'malo ofunikira kwambiri padziko lapansi.
